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 UUID uu
       was created.  Note that the UUID creation time is encoded  within  the
       UUID, and this function can only reasonably expect to extract the cre-
       ation time for UUIDs created with the uuid_generate(3)  function.   It
       may or may not work with UUIDs created by OSF DCE uuidgen.

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  gettimeof-
       day(2)).

AUTHOR
       uuid_time  was  written	by  Theodore  Y. Ts’o for the ext2 filesystem
       utilties.
