TIME(2) 			    Linux Programmer's Manual				  TIME(2)

NAME
       time - get time in seconds

SYNOPSIS
       #include <time.h>

       time_t time(time_t *t);

DESCRIPTION
       time  returns  the  time since the Epoch (00:00:00 UTC, January 1, 1970), measured in sec-
       onds.

       If t is non-NULL, the return value is also stored in the memory pointed to by t.

RETURN VALUE
       On success, the value of  time  in  seconds  since  the	Epoch  is  returned.   On  error,
       ((time_t)-1) is returned, and errno is set appropriately.

ERRORS
       EFAULT t points outside your accessible address space.

NOTES
       POSIX.1 defines seconds since the Epoch as a value to be interpreted as the number of sec-
       onds between a specified time and the Epoch, according to a formula  for  conversion  from
       UTC  equivalent	to  conversion	on  the naive basis that leap seconds are ignored and all
       years divisible by 4 are leap years.  This value is not the same as the actual  number  of
       seconds between the time and the Epoch, because of leap seconds and because clocks are not
       required to be synchronised to a standard reference.  The intention is that the	interpre-
       tation of seconds since the Epoch values be consistent; see POSIX.1 Annex B 2.2.2 for fur-
       ther rationale.

CONFORMING TO
       SVr4, SVID, POSIX, X/OPEN, BSD 4.3
       Under BSD 4.3, this call is obsoleted by gettimeofday(2).   POSIX  does	not  specify  any
       error conditions.
