NAME

time- get time

SYNOPSIS

#include <sys/types.h>

time_t time(time_t *tloc);

DESCRIPTION

The time() function returns the value of time in seconds since 00:00:00 UTC, January 1, 1970.

If tloc is non-zero, the return value is also stored in the location to which tloc points. If tloc points to an illegal address, time() fails and its actions are undefined.

RETURN VALUES

Upon successful completion, time() returns the value of time. Otherwise, (time_t)-1 is returned and errno is set to indicate the error.
