uuid_time - extract the time at which the UUID was created
time_t uuid_time(uuid_t uu, struct timeval *ret_tv)
function extracts the time at which the supplied time-based
was created. Note that the UUID creation time is only encoded

extract the creation time for UUIDs created with the
It may or may not work with UUIDs created by other mechanisms.
The time at which the UUID was created, in seconds since January 1, 1970 GMT

). 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
