NAME

       uuid_time - extract the time at which the UUID was created

SYNOPSIS

       #include <uuid.h>

       time_t uuid_time(uuid_t uu, struct timeval *ret_tv)

DESCRIPTION

       The uuid_time function extracts the time at which the supplied time-based UUID uu was created.  Note that
       the UUID creation time is only encoded within certain types of UUIDs.  This function can only  reasonably
       expect   to   extract   the   creation   time  for  UUIDs  created  with  the  uuid_generate_time(3)  and
       uuid_generate_time_safe(3) functions.  It may or may not work with UUIDs created by other mechanisms.

RETURN VALUES

       The time at which the UUID was created, in seconds since January 1, 1970 GMT  (the  epoch),  is  returned
       (see  time(2)).   The time at which the UUID was created, in seconds and microseconds since the epoch, is
       also stored in the location pointed to by ret_tv (see gettimeofday(2)).
