+.TH UUID_TIME 3 "May 2009" "util-linux" "Libuuid API"
+.SH NAME
+uuid_time \- extract the time at which the UUID was created
+.SH SYNOPSIS
+.nf
+.B #include <uuid.h>
+.sp
+.BI "time_t uuid_time(uuid_t " uu ", struct timeval *" ret_tv )
+.fi
+.SH DESCRIPTION
+The
+.B uuid_time
+function extracts the time at which the supplied time-based UUID
+.I 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
+.BR uuid_generate_time (3)
+and
+.BR uuid_generate_time_safe (3)
+functions.  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))."
