uuid_time(3) - Linux man page
Name
uuid_time - extract the time at which the UUID was created
Synopsis
#include <uuid/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 Values
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)).
