UUID_TIME(3)                   Libuuid API                  UUID_TIME(3)

NAME         top

       uuid_time - extract the time at which the UUID was created

SYNOPSIS         top

       #include <uuid.h>

       time_t uuid_time(uuid_t uu, struct timeval *ret_tv)

DESCRIPTION         top

       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) and
       uuid_generate_time_safe(3) functions.  It may or may not work
       with UUIDs created by other mechanisms.

RETURN VALUE         top

       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)).
