ANSI_SYNOPSIS
|

#include <time.h>
|

struct tm *gmtime(const time_t *<[clock]>);

TRAD_SYNOPSIS
|
|
#include <time.h>
|
|
struct tm *gmtime(<[clock]>)
|
|
const time_t *<[clock]>;
|
|
struct tm *gmtime_r(<[clock]>, <[res]>)

const time_t *<[clock]>;

DESCRIPTION
|
|
<<gmtime>> takes the time at <[clock]> representing the number
|
|
of elapsed seconds since 00:00:00 on January 1, 1970, Universal
|
|
Coordinated Time (UTC, also known in some countries as GMT,
|
|
Greenwich Mean time) and converts it to a <<struct tm>>
|
|
representation.
|
|
|
|
<<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>>).
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<gmtime>>.
|
|
|
|
<<gmtime>> requires no supporting OS subroutines.
