system_gmtime

The system_gmtime function is a thread-safe version of the standard gmtime function. It returns the current time adjusted to Greenwich Mean Time.

Syntax

struct tm *system_gmtime(const time_t *tp, const struct tm *res);

Returns

A pointer to a calendar time (tm) structure containing the GMT time. Depending on your system, the pointer may point to the data item represented by the second parameter, or it may point to a statically allocated item. For portability, do not assume either situation.

Parameters

time_t *tp is an arithmetic time.

tm *res is a pointer to a calendar time (tm) structure.

Example

time_t tp;struct tm res, *resp;tp = time(NULL);
	resp = system_gmtime(&tp, &res);
