Convert calendar time to a broken-down time
#include <time.h> struct tm* gmtime( const time_t* timer );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The gmtime() function converts the calendar time pointed to by timer into a broken-down time, expressed as Coordinated Universal Time (UTC) (formerly known as Greenwich Mean Time or GMT).
The gmtime() function places the converted time in a static
structure that's reused each time you call gmtime() or
could also change the data in this static buffer.
In a multithreaded application, use gmtime_r().
You typically use the date command to set the computer's internal clock using Coordinated Universal Time (UTC). Use the TZ environment variable or _CS_TIMEZONE configuration string to establish the local time zone. For more information, see “Setting the time zone” in the Configuring Your Environment chapter of the Neutrino User's Guide.
