gmtime
[convert time to UTC traditional form]
SYNOPSIS #include <time.h> struct tm *gmtime(const time_t *clock); struct tm *gmtime_r(const time_t *clock, struct tm *res);
DESCRIPTION
gmtime
assumes the time at clock
represents
a local time. gmtime
converts it to UTC (Universal Coordinated Time, also known in some countries
as GMT, Greenwich Mean time), then converts the representation from the
arithmetic representation to the traditional representation defined by
struct
tm.
gmtime constructs the traditional time representation in static storage; each call to gmtime or localtime will overwrite the information generated by previous calls to either function.
RETURNS
A pointer to the traditional time representation (struct
tm).
COMPLIANCE
ANSI C requires gmtime.
gmtime requires no supporting OS subroutines.
