NAME

       uuid_time - extract the time at which the UUID was created

SYNOPSIS

       #include <uuid/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)).
