1.18 +* FUNCTION
1.19 +* <<gmtime>>---convert time to UTC traditional form
1.20 +* INDEX
1.21 +* gmtime
1.22 +* ANSI_SYNOPSIS
1.23 +* #include <time.h>
1.24 +* struct tm *gmtime(const time_t *<[clock]>);
1.25 +* struct tm *gmtime_r(const time_t *<[clock]>, struct tm *<[res]>);
1.26 +* TRAD_SYNOPSIS
1.27 +* #include <time.h>
1.28 +* struct tm *gmtime(<[clock]>)
1.29 +* const time_t *<[clock]>;
1.30 +* struct tm *gmtime_r(<[clock]>, <[res]>)
1.31 +* const time_t *<[clock]>;
1.32 +* struct tm *<[res]>;
1.33 +* <<gmtime>> assumes the time at <[clock]> represents a local time.
1.34 +* <<gmtime>> converts it to UTC (Universal Coordinated Time, also known in some
1.35 +* countries as GMT, Greenwich Mean time), then converts the
1.36 +* representation from the arithmetic representation to
1.37 +* the traditional representation defined by <<struct tm>>.
1.38 +* <<gmtime>> constructs the traditional time representation in static
1.39 +* storage; each call to <<gmtime>> or <<localtime>> will overwrite the
1.40 +* information generated by previous calls to either function.
1.41 +* RETURNS
1.42 +* A pointer to the traditional time representation (<<struct tm>>).
1.43 +* PORTABILITY
1.44 +* ANSI C requires <<gmtime>>.
1.45 +* <<gmtime>> requires no supporting OS subroutines.
