The time() function returns the value of time in seconds since 0 hours, 0
minutes, 0 seconds, January 1, 1970, Coordinated Universal Time.
A copy of the time value may be saved to the area indicated by the
pointer tloc. If tloc is a NULL pointer, no value is stored.
Upon successful completion, time() returns the value of time. Otherwise
a value of ((time_t) -1) is returned and the global variable errno is set
to indicate the error.
The following error codes may be set in errno:
[EFAULT] An argument address referenced invalid memory.
The time() function conforms to ISO/IEC 9945-1:1990 (``POSIX.1'').
A time() function appeared in Version 6 AT&T UNIX.
