LIBRARY

SYNOPSIS

     #include <time.h>

DESCRIPTION

     The time() function returns the value of time in seconds since 0 hours, 0
     minutes, 0 seconds, January 1, 1970, Coordinated Universal Time.

     a value of ((time_t) -1) is returned and the global variable errno is set
     to indicate the error.


ERRORS

     The following error codes may be set in errno:

     [EFAULT]           An argument address referenced invalid memory.
