time - get time
time_t time(time_t *tloc);
time() returns the value of time in seconds since the Epoch.
If tloc is not a null pointer, the return value is also assigned to
the object to which it points.
Upon successful completion, time() returns the value of time.
Otherwise, a value of (time_t)-1 is returned and errno is set to
indicate the error.
[EFAULT] time() fails if tloc points to an illegal address. The
reliable detection of this error is implementation
date(1), gettimeofday(2), stime(2), ctime(3C), strftime(3C).
