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 seconds.

       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.

CONFORMING TO
       SVr4, 4.3BSD, C89, C99, POSIX.1-2001.  POSIX does not specify any error
       conditions.

NOTES
       POSIX.1 defines seconds since the Epoch as a value to be interpreted as
       the number of seconds 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 synchronized to a standard referÔÇÉ
       ence.  The intention is that the interpretation of  seconds  since  the
       Epoch  values  be  consistent;  see  POSIX.1  Annex B 2.2.2 for further
       rationale.
