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) function.  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)).
