NAME

       uuid_time - extract the time at which the UUID was created

SYNOPSIS

       #include <uuid.h>

       time_t uuid_time(uuid_t uu, struct timeval *ret_tv)

DESCRIPTION

       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

       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)).
