.SH SYNOPSIS
|
|
.nf
|
|

.SH DESCRIPTION
|
|
The
|
|
.B uuid_time
|
|
function extracts the time at which the supplied UUID
|
|
.I uu
|
|
was created. Note that the UUID creation time is encoded within the UUID,
|
|
and this function can only reasonably expect to extract the creation time
|
|
for UUIDs created with the
|
|
.BR uuid_generate (3)
|
|
function. It may or may not work with UUIDs created by OSF DCE
|
|
.BR uuidgen .
|
|
.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))."
