NAME

6       uuid_time - extract the time at which the UUID was created
7

SYNOPSIS

9       #include <uuid.h>
10
11       time_t uuid_time(uuid_t uu, struct timeval *ret_tv)
12

DESCRIPTION

14       The uuid_time() function extracts the time at which the supplied
15       time-based UUID uu was created. Note that the UUID creation time is
16       only encoded within certain types of UUIDs. This function can only
17       reasonably expect to extract the creation time for UUIDs created with
18       the uuid_generate_time(3) and uuid_generate_time_safe(3) functions. It
19       may or may not work with UUIDs created by other mechanisms.
20

RETURN VALUE

22       The time at which the UUID was created, in seconds since January 1,
23       1970 GMT (the epoch), is returned (see time(2)). The time at which the
24       UUID was created, in seconds and microseconds since the epoch, is also
25       stored in the location pointed to by ret_tv (see gettimeofday(2)).
