| .TH UUID_TIME 3 "@E2FSPROGS_MONTH@ @E2FSPROGS_YEAR@" "E2fsprogs version @E2FSPROGS_VERSION@" |
| .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 time-based UUID |
| .I 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 |
| .BR uuid_generate_time (3) |
| function. It may or may not work with UUIDs created by other mechanisms. |
| .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))." |
