// Mapping between EPOC32 time and libc time

// The basic philosophy is to work in time_t units (TInt) which
|
|
sl@0
|
17 |
// will be essentially TTimeIntervalSeconds from the start of Unix time.
|
|
sl@0
|
18 |
// To stay compliant with the C-Standard (with reference to C99 draft), we
|
|
sl@0
|
19 |
// set the meaning of time_t to be Universal time.

Intended Usage: The gettimeofday function obtains the current UTC time, which is
|
|
sl@0
|
34 |
expressed as seconds and microseconds since 00:00:00 Coordinated Universal Time (UTC),
|
|
sl@0
|
35 |
January 1, 1970, and stores it in a timeval structure.
|
|
sl@0
|
36 |
Please note that tz_minuteswest includes daytime saving. The struct member tz_dsttime is no
|
|
sl@0
|
37 |
longer supported by Symbian OS and therefore set to Zero.
