// Description:
// TIME.CPP
// Mapping between EPOC32 time and libc time
// The basic philosophy is to work in time_t units (TInt) which
// will be essentially TTimeIntervalSeconds from the start of Unix time.
// To stay compliant with the C-Standard (with reference to C99 draft), we
// set the meaning of time_t to be Universal time.
//

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