gmtime function — Extracts parts of a UTC time

Synopsis

tm* gmtime(const time_t* timeptr)

The gmtime function expands the calendar time pointed to by timeptr into a static tm object using Coordinated Universal Time (UTC). It returns a pointer to the static object. Subsequent calls to gmtime overwrite the object. The static object can be shared with localtime.

If UTC is not available (for example, the host operating system does not provide the time zone offset), a null pointer is returned.
