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)).
