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 +.BR uuid_generate_time (3) +function. It may or may not work with UUIDs created by other mechanisms. +.SH "RETURN VALUES" +The time at which the UUID was created, in seconds since January 1, 1970 GMT +(the epoch), is returned (see +.BR 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 +.I ret_tv +(see +.BR gettimeofday "(2))." +.SH AUTHOR +Theodore Y.
