Many of the formatting commands use the

system's locale settings for the date and time, for example the characters

sl@0
|
1692 |
used to separate components of the date and time and the ordering of day,
|
sl@0
|
1693 |
month and year. The list of formatting commands below is divided into two
|
sl@0
|
1694 |
sections, the first of which lists the commands which operate without reference
|
sl@0
|
1695 |
to the locale's date and time settings (see class TLocale) and the second
|
sl@0
|
1696 |
table lists the commands which do use these settings.
|
sl@0
|
1697 |
|
sl@0
|
1698 |
The following formatting commands do not honour the locale-specific system
|
sl@0
|
1699 |
settings:
|
sl@0
|
1700 |
|
sl@0
|
1701 |
\%\% : Include a single '%' character in the string
|
sl@0
|
1702 |
|
sl@0
|
1703 |
\%* : Abbreviate following item (the following item should not be preceded
|
sl@0
|
1704 |
by a '%' character).
|
sl@0
|
1705 |
|
sl@0
|
1706 |
\%C : Interpret the argument as the six digit microsecond component of the
|
sl@0
|
1707 |
time. In its abbreviated form, ('%*C') this should be followed by an integer
|
sl@0
|
1708 |
between zero and six, where the integer indicates the number of digits to display.
|
sl@0
|
1709 |
|
sl@0
|
1710 |
\%D : Interpret the argument as the two digit day number in the month. Abbreviation
|
sl@0
|
1711 |
suppresses leading zero.
|
sl@0
|
1712 |
|
sl@0
|
1713 |
\%E : Interpret the argument as the day name. Abbreviation is language-specific
|
sl@0
|
1714 |
(e.g. English uses the first three letters).
|
sl@0
|
1715 |
|
sl@0
|
1716 |
\%F : Use this command for locale-independent ordering of date components.
|
sl@0
|
1717 |
This orders the following day/month/year component(s) (\%D, \%M, \%Y for example)
|
sl@0
|
1718 |
according to the order in which they are specified in the string. This removes
|
sl@0
|
1719 |
the need to use \%1 to \%5 (described below).
|
sl@0
|
1720 |
|
sl@0
|
1721 |
\%H : Interpret the argument as the one or two digit hour component of the
|
sl@0
|
1722 |
time in 24 hour time format. Abbreviation suppresses leading zero. For locale-dependent
|
sl@0
|
1723 |
hour formatting, use \%J.
|
sl@0
|
1724 |
|
sl@0
|
1725 |
\%I : Interpret the argument as the one or two digit hour component of the
|
sl@0
|
1726 |
time in 12 hour time format. The leading zero is automatically suppressed
|
sl@0
|
1727 |
so that abbreviation has no effect. For locale-dependent hour formatting,
|
sl@0
|
1728 |
use \%J.
|
sl@0
|
1729 |
|
sl@0
|
1730 |
\%M : Interpret the argument as the one or two digit month number. Abbreviation
|
sl@0
|
1731 |
suppresses leading zero.
|
sl@0
|
1732 |
|
sl@0
|
1733 |
\%N : Interpret the argument as the month name. Abbreviation is language specific, e.g.
|
sl@0
|
1734 |
English uses the first three letters only. When using locale-dependent formatting,
|
sl@0
|
1735 |
(that is, \%F has not previously been specified), specifying \%N causes any
|
sl@0
|
1736 |
subsequent occurrence of a month specifier in the string to insert the month
|
sl@0
|
1737 |
as text rather than in numeric form. When using locale-independent formatting,
|
sl@0
|
1738 |
specifying \%N causes the month to be inserted as text at that position, but
|
sl@0
|
1739 |
any subsequent occurrence of \%M will cause the month to be inserted in numeric
|
sl@0
|
1740 |
form.
|
sl@0
|
1741 |
|
sl@0
|
1742 |
\%S : Interpret the argument as the one or two digit seconds component of the
|
sl@0
|
1743 |
time. Abbreviation suppresses leading zero.
|
sl@0
|
1744 |
|
sl@0
|
1745 |
\%T : Interpret the argument as the one or two digit minutes component of the
|
sl@0
|
1746 |
time. Abbreviation suppresses leading zero.
|
sl@0
|
1747 |
|
sl@0
|
1748 |
\%W : Interpret the argument as the one or two digit week number in year. Abbreviation
|
sl@0
|
1749 |
suppresses leading zero.
|
sl@0
|
1750 |
|
sl@0
|
1751 |
\%X : Interpret the argument as the date suffix. Cannot be abbreviated. When
|
sl@0
|
1752 |
using locale-dependent formatting (that is, \%F has not previously been specified),
|
sl@0
|
1753 |
\%X causes all further occurrences of the day number to be displayed with the
|
sl@0
|
1754 |
date suffix. When using locale-independent formatting, a date suffix will
|
sl@0
|
1755 |
be inserted only after the occurrence of the day number which \%X follows in
|
sl@0
|
1756 |
the format string. Any further occurrence of \%D without a following \%X will
|
sl@0
|
1757 |
insert the day number without a suffix.
|
sl@0
|
1758 |
|
sl@0
|
1759 |
\%Y : Interpret the argument as the four digit year number. Abbreviation suppresses
|
sl@0
|
1760 |
the first two digits.
|
sl@0
|
1761 |
|
sl@0
|
1762 |
\%Z : Interpret the argument as the one, two or three digit day number in the
|
sl@0
|
1763 |
year. Abbreviation suppresses leading zeros.
|
sl@0
|
1764 |
|
sl@0
|
1765 |
The following formatting commands do honour the locale-specific system settings:
|
sl@0
|
1766 |
|
sl@0
|
1767 |
\%. : Interpret the argument as the decimal separator character (as set by
|
sl@0
|
1768 |
TLocale::SetDecimalSeparator()). The decimal separator is used to separate
|
sl@0
|
1769 |
seconds and microseconds, if present.
|
sl@0
|
1770 |
|
sl@0
|
1771 |
\%: : Interpret the argument as one of the four time separator characters (as
|
sl@0
|
1772 |
set by TLocale::SetTimeSeparator()). Must be followed by an integer between
|
sl@0
|
1773 |
zero and three inclusive to indicate which time separator character is being
|
sl@0
|
1774 |
referred to.
|
sl@0
|
1775 |
|
sl@0
|
1776 |
\%/ : Interpret the argument as one of the four date separator characters (as
|
sl@0
|
1777 |
set by TLocale::SetDateSeparator()). Must be followed by an integer between
|
sl@0
|
1778 |
zero and three inclusive to indicate which date separator character is being
|
sl@0
|
1779 |
referred to.
|
sl@0
|
1780 |
|
sl@0
|
1781 |
\%1 : Interpret the argument as the first component of a three component date
|
sl@0
|
1782 |
(i.e. day, month or year) where the order has been set by TLocale::SetDateFormat().
|
sl@0
|
1783 |
When the date format is EDateEuropean, this is the day, when EDateAmerican,
|
sl@0
|
1784 |
the month, and when EDateJapanese, the year. For more information on this
|
sl@0
|
1785 |
and the following four formatting commands, see the Notes section immediately
|
sl@0
|
1786 |
below.
|
sl@0
|
1787 |
|
sl@0
|
1788 |
\%2 : Interpret the argument as the second component of a three component date
|
sl@0
|
1789 |
where the order has been set by TLocale::SetDateFormat(). When the date format
|
sl@0
|
1790 |

|
sl@0
|
1791 |
EDateJapanese, the month.
|
sl@0
|
1792 |
|
sl@0
|
1793 |
\%3 : Interpret the argument as the third component of a three component date
|
sl@0
|
1794 |
where the order has been set by TLocale::SetDateFormat(). When the date format
|
sl@0
|
1795 |
is EDateEuropean, or EDateAmerican this is the year and when EDateJapanese,
|
sl@0
|
1796 |
the day.
|
sl@0
|
1797 |
|
sl@0
|
1798 |
\%4 : Interpret the argument as the first component of a two component date
|
sl@0
|
1799 |
(day and month) where the order has been set by TLocale::SetDateFormat().
|
sl@0
|
1800 |
When the date format is EDateEuropean this is the day, and when EDateAmerican
|
sl@0
|
1801 |
or EDateJapanese, the month.
|
sl@0
|
1802 |
|
sl@0
|
1803 |
\%5 : Interpret the argument as the second component of a two component date
|
sl@0
|
1804 |
(day and month) where the order has been set by TLocale::SetDateFormat().
|
sl@0
|
1805 |
When the date format is EDateEuropean this is the month, and when EDateAmerican
|
sl@0
|
1806 |
or EDateJapanese, the day.
|
sl@0
|
1807 |
|
sl@0
|
1808 |
\%A : Interpret the argument as "am" or "pm" text according to the current
|
sl@0
|
1809 |
language and time of day. Unlike the \%B formatting command (described below),
|
sl@0
|
1810 |
\%A disregards the locale's 12 or 24 hour clock setting, so that when used
|
sl@0
|
1811 |
without an inserted + or - sign, am/pm text will always be displayed. Whether
|
sl@0
|
1812 |
a space is inserted between the am/pm text and the time depends on the locale-specific
|
sl@0
|
1813 |
settings. However, if abbreviated (\%*A), no space is inserted, regardless
|
sl@0
|
1814 |
of the locale's settings. The am/pm text appears before or after the time,
|
sl@0
|
1815 |
according to the position of the \%A, regardless of the locale-specific settings.
|
sl@0
|
1816 |
For example, the following ordering of formatting commands causes am/pm text
|
sl@0
|
1817 |
to be printed after the time: \%H \%T \%S \%A. Optionally, a minus or plus sign
|
sl@0
|
1818 |
may be inserted between the "%" and the "A". This operates as follows:
|
sl@0
|
1819 |
|
sl@0
|
1820 |
\%-A causes am/pm text to be inserted into the descriptor only if the am/pm
|
sl@0
|
1821 |
symbol position has been set in the locale to ELocaleBefore. Cannot be abbreviated
|
sl@0
|
1822 |
using asterisk.
|
sl@0
|
1823 |
|
sl@0
|
1824 |
\%+A causes am/pm text to be inserted into the descriptor only if the am/pm
|
sl@0
|
1825 |
symbol position has been set in the locale to ELocaleAfter. Cannot be abbreviated
|
sl@0
|
1826 |
using asterisk. For example, the following formatting commands will cause
|
sl@0
|
1827 |
am/pm text to be displayed after the time if the am/pm position has been set
|
sl@0
|
1828 |
in the locale to ELocaleAfter or before the time if ELocaleBefore: \%-A \%H
|
sl@0
|
1829 |
\%T \%S \%+A.
|
sl@0
|
1830 |
|
sl@0
|
1831 |
\%B Interpret the argument as am or pm text according to the current language
|
sl@0
|
1832 |
and time of day. Unlike the \%A command, when using \%B, am/pm text is displayed
|
sl@0
|
1833 |
only if the clock setting in the locale is 12-hour. Whether a space is inserted
|
sl@0
|
1834 |
between the am/pm text and the time depends on the locale-specific settings.
|
sl@0
|
1835 |
However, if abbreviated (\%*B), no space is inserted, regardless of the locale's
|
sl@0
|
1836 |
settings. The am/pm text appears before or after the time, according to the
|
sl@0
|
1837 |
location of the "%B", regardless of the locale-specific settings. For example,
|
sl@0
|
1838 |
the following formatting commands cause am/pm text to be printed after the
|
sl@0
|
1839 |
time: \%H \%T \%S \%B. Optionally, a minus or plus sign may be inserted between
|
sl@0
|
1840 |
the "%" and the "B". This operates as follows:
|
sl@0
|
1841 |
|
sl@0
|
1842 |
\%-B causes am/pm text to be inserted into the descriptor only if using a 12
|
sl@0
|
1843 |
hour clock and the am/pm symbol position has been set in the locale to ELocaleBefore.
|
sl@0
|
1844 |
Cannot be abbreviated using asterisk.
|
sl@0
|
1845 |
|
sl@0
|
1846 |
\%+B causes am/pm text to be inserted into the descriptor only if using a 12
|
sl@0
|
1847 |
hour clock and the am/pm symbol position has been set in the locale to ELocaleAfter.
|
sl@0
|
1848 |
Cannot be abbreviated using asterisk. For example, the following formatting
|
sl@0
|
1849 |
commands cause am/pm text to be printed after the time if the am/pm position
|
sl@0
|
1850 |
has been set in the locale to ELocaleAfter or before the time if ELocaleBefore:
|
sl@0
|
1851 |
\%-B \%H \%T \%S \%+B.
|
sl@0
|
1852 |
|
sl@0
|
1853 |
\%J Interpret the argument as the hour component of the time in either 12 or
|
sl@0
|
1854 |
24 hour clock format depending on the locale's clock format setting. When
|
sl@0
|
1855 |
the clock format has been set to 12 hour, leading zeros are automatically
|
sl@0
|
1856 |
suppressed so that abbreviation has no effect. Abbreviation suppresses leading
|
sl@0
|
1857 |
zero only when using a 24 hour clock.
|
sl@0
|
1858 |
|
sl@0

Notes:
|
sl@0
|
1860 |
|
sl@0
|
1861 |
The \%1, \%2, \%3, \%4 and \%5 formatting commands are used in conjunction with
|
sl@0
|
1862 |
\%D, \%M and \%Y to format the date locale-dependently. When formatting the date
|
sl@0
|
1863 |
locale-dependently, the order of the day, month and year components within
|
sl@0
|
1864 |
the string is determined by the order of the \%1 to \%5 formatting commands,
|
sl@0
|
1865 |
not that of \%D, \%M, \%Y.
|
sl@0
|
1866 |
|
sl@0
|
1867 |
When formatting the date locale-independently (that is, \%F has been specified
|
sl@0
|
1868 |
in the format string), the \%1 to \%5 formatting commands are not required,
|
sl@0
|
1869 |
and should be omitted. In this case, the order of the date components is determined
|
sl@0
|
1870 |
by the order of the \%D, \%M, \%Y format commands within aFormat.
|
sl@0
|
1871 |
|
sl@0
|
1872 |
Up to four date separators and up to four time separators can be used to separate
|
sl@0
|
1873 |
the components of a date or time. When formatting a numerical date consisting
|
sl@0
|
1874 |
of the day, month and year or a time containing hours, minutes and seconds,
|
sl@0
|
1875 |
all four separators should always be specified in the format command string.
|
sl@0
|
1876 |
Usually, the leading and trailing separators should not be displayed. In this
|
sl@0
|
1877 |
case, the first and fourth separators should still be specified, but should
|
sl@0
|
1878 |
be represented by a null character.
|
sl@0
|
1879 |
|
sl@0
|
1880 |
The date format follows the pattern:
|
sl@0
|
1881 |
|
sl@0
|
1882 |
DateSeparator[0] DateComponent1 DateSeparator[1] DateComponent2 DateSeparator[2]
|
sl@0
|
1883 |
DateComponent3 DateSeparator[3]
|
sl@0
|
1884 |
|
sl@0
|
1885 |
where the ordering of date components is determined by the locale's date format
|
sl@0
|
1886 |
setting.
|
sl@0
|
1887 |
|
sl@0
|
1888 |
The time format follows the pattern:
|
sl@0
|
1889 |
|
sl@0
|
1890 |
TimeSeparator[0] Hours TimeSeparator[1] Minutes TimeSeparator[2] Seconds TimeSeparator[3]
|
sl@0
|
1891 |
|
sl@0
|
1892 |
If the time includes a microseconds component, the third separator should
|
sl@0
|
1893 |
occur after the microseconds, and the seconds and microseconds should be separated
|
sl@0
|
1894 |
by the decimal separator. When formatting a two component time, the following
|
sl@0
|
1895 |
rules apply:
|
sl@0
|
1896 |
|
sl@0
|
1897 |
if the time consists of hours and minutes, the third time delimiter should
|
sl@0
|
1898 |
be omitted
|
sl@0
|
1899 |
|
sl@0
|
1900 |
if the time consists of minutes and seconds, the second time delimiter should
|
sl@0
|
1901 |
be omitted
|
sl@0
|
1902 |
|
sl@0
|
1903 |
@param aDes Descriptor, which, on return contains the formatted date/time string.
|
sl@0
|
1904 |
@param aFormat Format string which determines the format of the date and time.
|
sl@0
|
1905 |
|
sl@0
|
1906 |
@leave KErrOverflow The date/time string is too long for the descriptor aDes.

Many of the formatting commands use the
|
sl@0
|
1923 |
system's locale settings for the date and time, for example the characters
|
sl@0
|
1924 |
used to separate components of the date and time and the ordering of day,
|
sl@0
|
1925 |
month and year. The list of formatting commands below is divided into two
|
sl@0
|
1926 |
sections, the first of which lists the commands which operate without reference
|
sl@0
|
1927 |
to the locale's date and time settings (see class TLocale) and the second
|
sl@0
|
1928 |
table lists the commands which do use these settings.
|
sl@0
|
1929 |
|
sl@0
|
1930 |
The following formatting commands do not honour the locale-specific system
|
sl@0
|
1931 |
settings:
|
sl@0
|
1932 |
|
sl@0
|
1933 |
\%\% : Include a single '%' character in the string
|
sl@0
|
1934 |
|
sl@0
|
1935 |
\%* : Abbreviate following item (the following item should not be preceded
|
sl@0
|
1936 |
by a '%' character).
|
sl@0
|
1937 |
|
sl@0
|
1938 |
\%C : Interpret the argument as the six digit microsecond component of the
|
sl@0
|
1939 |
time. In its abbreviated form, ('%*C') this should be followed by an integer
|
sl@0
|
1940 |
between zero and six, where the integer indicates the number of digits to display.
|
sl@0
|
1941 |
|
sl@0
|
1942 |
\%D : Interpret the argument as the two digit day number in the month. Abbreviation
|
sl@0
|
1943 |
suppresses leading zero.
|
sl@0
|
1944 |
|
sl@0
|
1945 |
\%E : Interpret the argument as the day name. Abbreviation is language-specific
|
sl@0
|
1946 |
(e.g. English uses the first three letters).
|
sl@0
|
1947 |
|
sl@0
|
1948 |
\%F : Use this command for locale-independent ordering of date components.
|
sl@0
|
1949 |
This orders the following day/month/year component(s) (\%D, \%M, \%Y for example)
|
sl@0
|
1950 |
according to the order in which they are specified in the string. This removes
|
sl@0
|
1951 |
the need to use \%1 to \%5 (described below).
|
sl@0
|
1952 |
|
sl@0
|
1953 |
\%H : Interpret the argument as the one or two digit hour component of the
|
sl@0
|
1954 |
time in 24 hour time format. Abbreviation suppresses leading zero. For locale-dependent
|
sl@0
|
1955 |
hour formatting, use \%J.
|
sl@0
|
1956 |
|
sl@0
|
1957 |
\%I : Interpret the argument as the one or two digit hour component of the
|
sl@0
|
1958 |
time in 12 hour time format. The leading zero is automatically suppressed
|
sl@0
|
1959 |
so that abbreviation has no effect. For locale-dependent hour formatting,
|
sl@0
|
1960 |
use \%J.
|
sl@0
|
1961 |
|
sl@0
|
1962 |
\%M : Interpret the argument as the one or two digit month number. Abbreviation
|
sl@0
|
1963 |
suppresses leading zero.
|
sl@0
|
1964 |
|
sl@0
|
1965 |
\%N : Interpret the argument as the month name. Abbreviation is language specific, e.g.
|
sl@0
|
1966 |
English uses the first three letters only. When using locale-dependent formatting,
|
sl@0
|
1967 |
(that is, \%F has not previously been specified), specifying \%N causes any
|
sl@0
|
1968 |
subsequent occurrence of a month specifier in the string to insert the month
|
sl@0
|
1969 |
as text rather than in numeric form. When using locale-independent formatting,
|
sl@0
|
1970 |
specifying \%N causes the month to be inserted as text at that position, but
|
sl@0
|
1971 |
any subsequent occurrence of \%M will cause the month to be inserted in numeric
|
sl@0
|
1972 |
form.
|
sl@0
|
1973 |
|
sl@0
|
1974 |
\%S : Interpret the argument as the one or two digit seconds component of the
|
sl@0
|
1975 |
time. Abbreviation suppresses leading zero.
|
sl@0
|
1976 |
|
sl@0
|
1977 |
\%T : Interpret the argument as the one or two digit minutes component of the
|
sl@0
|
1978 |
time. Abbreviation suppresses leading zero.
|
sl@0
|
1979 |
|
sl@0
|
1980 |
\%W : Interpret the argument as the one or two digit week number in year. Abbreviation
|
sl@0
|
1981 |
suppresses leading zero.
|
sl@0
|
1982 |
|
sl@0
|
1983 |
\%X : Interpret the argument as the date suffix. Cannot be abbreviated. When
|
sl@0
|
1984 |
using locale-dependent formatting (that is, \%F has not previously been specified),
|
sl@0
|
1985 |
\%X causes all further occurrences of the day number to be displayed with the
|
sl@0
|
1986 |
date suffix. When using locale-independent formatting, a date suffix will
|
sl@0
|
1987 |
be inserted only after the occurrence of the day number which \%X follows in
|
sl@0
|
1988 |
the format string. Any further occurrence of \%D without a following \%X will
|
sl@0
|
1989 |
insert the day number without a suffix.
|
sl@0
|
1990 |
|
sl@0
|
1991 |
\%Y : Interpret the argument as the four digit year number. Abbreviation suppresses
|
sl@0
|
1992 |
the first two digits.
|
sl@0
|
1993 |
|
sl@0
|
1994 |
\%Z : Interpret the argument as the one, two or three digit day number in the
|
sl@0
|
1995 |
year. Abbreviation suppresses leading zeros.
|
sl@0
|
1996 |
|
sl@0
|
1997 |
The following formatting commands do honour the locale-specific system settings:
|
sl@0
|
1998 |
|
sl@0
|
1999 |
\%. : Interpret the argument as the decimal separator character (as set by
|
sl@0
|
2000 |
TLocale::SetDecimalSeparator()). The decimal separator is used to separate
|
sl@0
|
2001 |
seconds and microseconds, if present.
|
sl@0
|
2002 |
|
sl@0
|
2003 |
\%: : Interpret the argument as one of the four time separator characters (as
|
sl@0
|
2004 |
set by TLocale::SetTimeSeparator()). Must be followed by an integer between
|
sl@0
|
2005 |
zero and three inclusive to indicate which time separator character is being
|
sl@0
|
2006 |
referred to.
|
sl@0
|
2007 |
|
sl@0
|
2008 |
\%/ : Interpret the argument as one of the four date separator characters (as
|
sl@0
|
2009 |
set by TLocale::SetDateSeparator()). Must be followed by an integer between
|
sl@0
|
2010 |
zero and three inclusive to indicate which date separator character is being
|
sl@0
|
2011 |
referred to.
|
sl@0
|
2012 |
|
sl@0
|
2013 |
\%1 : Interpret the argument as the first component of a three component date
|
sl@0
|
2014 |
(i.e. day, month or year) where the order has been set by TLocale::SetDateFormat().
|
sl@0
|
2015 |
When the date format is EDateEuropean, this is the day, when EDateAmerican,
|
sl@0
|
2016 |
the month, and when EDateJapanese, the year. For more information on this
|
sl@0
|
2017 |
and the following four formatting commands, see the Notes section immediately
|
sl@0
|
2018 |
below.
|
sl@0
|
2019 |
|
sl@0
|
2020 |
\%2 : Interpret the argument as the second component of a three component date
|
sl@0
|
2021 |
where the order has been set by TLocale::SetDateFormat(). When the date format
|
sl@0
|
2022 |
is EDateEuropean, this is the month, when EDateAmerican, the day and when
|
sl@0
|
2023 |
EDateJapanese, the month.
|
sl@0
|
2024 |
|
sl@0
|
2025 |
\%3 : Interpret the argument as the third component of a three component date
|
sl@0
|
2026 |
where the order has been set by TLocale::SetDateFormat(). When the date format
|
sl@0
|
2027 |
is EDateEuropean, or EDateAmerican this is the year and when EDateJapanese,
|
sl@0
|
2028 |
the day.
|
sl@0
|
2029 |
|
sl@0
|
2030 |
\%4 : Interpret the argument as the first component of a two component date
|
sl@0
|
2031 |
(day and month) where the order has been set by TLocale::SetDateFormat().
|
sl@0
|
2032 |
When the date format is EDateEuropean this is the day, and when EDateAmerican
|
sl@0
|
2033 |
or EDateJapanese, the month.
|
sl@0
|
2034 |
|
sl@0
|
2035 |
\%5 : Interpret the argument as the second component of a two component date
|
sl@0
|
2036 |
(day and month) where the order has been set by TLocale::SetDateFormat().
|
sl@0
|
2037 |
When the date format is EDateEuropean this is the month, and when EDateAmerican
|
sl@0
|
2038 |
or EDateJapanese, the day.
|
sl@0
|
2039 |
|
sl@0
|
2040 |
\%A : Interpret the argument as "am" or "pm" text according to the current
|
sl@0
|
2041 |
language and time of day. Unlike the \%B formatting command (described below),
|
sl@0
|
2042 |
\%A disregards the locale's 12 or 24 hour clock setting, so that when used
|
sl@0
|
2043 |
without an inserted + or - sign, am/pm text will always be displayed. Whether
|
sl@0
|
2044 |
a space is inserted between the am/pm text and the time depends on the locale-specific
|
sl@0
|
2045 |
settings. However, if abbreviated (\%*A), no space is inserted, regardless
|
sl@0
|
2046 |
of the locale's settings. The am/pm text appears before or after the time,
|
sl@0
|
2047 |
according to the position of the \%A, regardless of the locale-specific settings.
|
sl@0
|
2048 |
For example, the following ordering of formatting commands causes am/pm text
|
sl@0
|
2049 |
to be printed after the time: \%H \%T \%S \%A. Optionally, a minus or plus sign
|
sl@0
|
2050 |
may be inserted between the "%" and the "A". This operates as follows:
|
sl@0
|
2051 |
|
sl@0
|
2052 |
\%-A causes am/pm text to be inserted into the descriptor only if the am/pm
|
sl@0
|
2053 |
symbol position has been set in the locale to ELocaleBefore. Cannot be abbreviated
|
sl@0
|
2054 |
using asterisk.
|
sl@0
|
2055 |
|

2056 |
\%+A causes am/pm text to be inserted into the descriptor only if the am/pm
|
sl@0
|
2057 |
symbol position has been set in the locale to ELocaleAfter. Cannot be abbreviated
|
sl@0
|
2058 |
using asterisk. For example, the following formatting commands will cause
|
sl@0
|
2059 |
am/pm text to be displayed after the time if the am/pm position has been set
|
sl@0
|
2060 |
in the locale to ELocaleAfter or before the time if ELocaleBefore: \%-A \%H
|
sl@0
|
2061 |
\%T \%S \%+A.
|
sl@0
|
2062 |
|
sl@0
|
2063 |
\%B Interpret the argument as am or pm text according to the current language
|
sl@0
|
2064 |
and time of day. Unlike the \%A command, when using \%B, am/pm text is displayed
|
sl@0
|
2065 |
only if the clock setting in the locale is 12-hour. Whether a space is inserted
|
sl@0
|
2066 |
between the am/pm text and the time depends on the locale-specific settings.
|
sl@0
|
2067 |
However, if abbreviated (\%*B), no space is inserted, regardless of the locale's
|
sl@0
|
2068 |
settings. The am/pm text appears before or after the time, according to the
|
sl@0
|
2069 |
location of the "%B", regardless of the locale-specific settings. For example,
|
sl@0
|
2070 |
the following formatting commands cause am/pm text to be printed after the
|
sl@0
|
2071 |
time: \%H \%T \%S \%B. Optionally, a minus or plus sign may be inserted between
|
sl@0
|
2072 |
the "%" and the "B". This operates as follows:
|
sl@0
|
2073 |
|
sl@0
|
2074 |
\%-B causes am/pm text to be inserted into the descriptor only if using a 12
|
sl@0
|
2075 |
hour clock and the am/pm symbol position has been set in the locale to ELocaleBefore.
|
sl@0
|
2076 |
Cannot be abbreviated using asterisk.
|
sl@0
|
2077 |
|
sl@0
|
2078 |
\%+B causes am/pm text to be inserted into the descriptor only if using a 12
|
sl@0
|
2079 |
hour clock and the am/pm symbol position has been set in the locale to ELocaleAfter.
|
sl@0
|
2080 |
Cannot be abbreviated using asterisk. For example, the following formatting
|
sl@0
|
2081 |
commands cause am/pm text to be printed after the time if the am/pm position
|
sl@0
|
2082 |
has been set in the locale to ELocaleAfter or before the time if ELocaleBefore:
|
sl@0
|
2083 |
\%-B \%H \%T \%S \%+B.
|
sl@0
|
2084 |
|
sl@0
|
2085 |
\%J Interpret the argument as the hour component of the time in either 12 or
|
sl@0
|
2086 |
24 hour clock format depending on the locale's clock format setting. When
|
sl@0
|
2087 |
the clock format has been set to 12 hour, leading zeros are automatically
|
sl@0
|
2088 |
suppressed so that abbreviation has no effect. Abbreviation suppresses leading
|
sl@0
|
2089 |
zero only when using a 24 hour clock.
|

Notes:
|
sl@0
|
2092 |
|
sl@0
|
2093 |
The \%1, \%2, \%3, \%4 and \%5 formatting commands are used in conjunction with
|
sl@0
|
2094 |
\%D, \%M and \%Y to format the date locale-dependently. When formatting the date
|
sl@0
|
2095 |
locale-dependently, the order of the day, month and year components within
|
sl@0
|
2096 |
the string is determined by the order of the \%1 to \%5 formatting commands,
|
sl@0
|
2097 |
not that of \%D, \%M, \%Y.
|
sl@0
|
2098 |
|
sl@0
|
2099 |
When formatting the date locale-independently (that is, \%F has been specified
|
sl@0
|
2100 |
in the format string), the \%1 to \%5 formatting commands are not required,
|
sl@0
|
2101 |
and should be omitted. In this case, the order of the date components is determined
|
sl@0
|
2102 |
by the order of the \%D, \%M, \%Y format commands within aFormat.
|
sl@0
|
2103 |
|
sl@0
|
2104 |
Up to four date separators and up to four time separators can be used to separate
|
sl@0
|
2105 |
the components of a date or time. When formatting a numerical date consisting
|
sl@0
|
2106 |
of the day, month and year or a time containing hours, minutes and seconds,
|
sl@0
|
2107 |
all four separators should always be specified in the format command string.
|
sl@0
|
2108 |
Usually, the leading and trailing separators should not be displayed. In this
|
sl@0
|
2109 |
case, the first and fourth separators should still be specified, but should
|
sl@0
|
2110 |
be represented by a null character.
|
sl@0
|
2111 |
|
sl@0
|
2112 |
The date format follows the pattern:
|
sl@0
|
2113 |
|
sl@0
|
2114 |
DateSeparator[0] DateComponent1 DateSeparator[1] DateComponent2 DateSeparator[2]
|
sl@0
|
2115 |
DateComponent3 DateSeparator[3]
|
sl@0
|
2116 |
|
sl@0
|
2117 |
where the ordering of date components is determined by the locale's date format
|
sl@0
|
2118 |
setting.
|
sl@0
|
2119 |
|
sl@0
|
2120 |
The time format follows the pattern:
|
sl@0
|
2121 |
|
sl@0
|
2122 |
TimeSeparator[0] Hours TimeSeparator[1] Minutes TimeSeparator[2] Seconds TimeSeparator[3]
|
sl@0
|
2123 |
|
sl@0
|
2124 |
If the time includes a microseconds component, the third separator should
|
sl@0
|
2125 |
occur after the microseconds, and the seconds and microseconds should be separated
|
sl@0
|
2126 |
by the decimal separator. When formatting a two component time, the following
|
sl@0
|
2127 |
rules apply:
|
sl@0
|
2128 |
|
sl@0
|
2129 |
if the time consists of hours and minutes, the third time delimiter should
|
sl@0
|
2130 |
be omitted
|
sl@0
|
2131 |
|
sl@0
|
2132 |
if the time consists of minutes and seconds, the second time delimiter should
|
sl@0
|
2133 |
be omitted
|
sl@0
|
2134 |
|
sl@0
|
2135 |
@param aDes Descriptor, which, on return contains the formatted date/time string.
|
sl@0
|
2136 |
@param aFormat Format string which determines the format of the date and time.
|
sl@0
|
2137 |
@param aLocale Specific locale which formatting will be based on.
|
