| .SH NAME |
| uuid_time \- extract the time at which the UUID was created |
| .SH SYNOPSIS |
| .nf |
| .B #include <uuid/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 UUID |
| .I uu |
| was created. Note that the UUID creation time is encoded within the UUID, |
| and this function can only reasonably expect to extract the creation time |
| for UUIDs created with the |
| .BR uuid_generate (3) |
| function. It may or may not work with UUIDs created by OSF DCE |
| .BR uuidgen . |
| .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))." |
