C 4 time - get time of day

 #include <sys/types.h> 
 time_t time(tloc)  time_t *tloc; 

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

The argument tloc points to an area where the return value is also stored. 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 errno is set to indicate the error.

The following error codes may be set in errno :

15 [EFAULT] An argument address referenced invalid memory.

gettimeofday(2), ctime(3)
