| 33 | .SH NAME |
| 34 | uuid_time \- extract the time at which the UUID was created |
| 35 | .SH SYNOPSIS |
| 36 | .nf |
| 37 | .B #include <uuid/uuid.h> |
| 38 | .sp |
| 39 | .BI "time_t uuid_time(uuid_t " uu ", struct timeval *" ret_tv ) |
| 40 | .fi |
| 41 | .SH DESCRIPTION |
| 42 | The |
| 43 | .B uuid_time |
| 44 | function extracts the time at which the supplied UUID |
| 45 | .I uu |
| 46 | was created. Note that the UUID creation time is encoded within the UUID, |
| 47 | and this function can only reasonably expect to extract the creation time |
| 48 | for UUIDs created with the |
| 49 | .BR uuid_generate (3) |
| 50 | function. It may or may not work with UUIDs created by OSF DCE |
| 51 | .BR uuidgen . |
| 52 | .SH "RETURN VALUES" |
| 53 | The time at which the UUID was created, in seconds since January 1, 1970 GMT |
| 54 | (the epoch), is returned (see |
| 55 | .BR time "(2))." |
| 56 | The time at which the UUID was created, in seconds and microseconds since |
| 57 | the epoch, is also stored in the location pointed to by |
| 58 | .I ret_tv |
| 59 | (see |
| 60 | .BR gettimeofday "(2))." |
