What format is $dirent->time() ?

Using the SVN::Client to browse a repository, I use SVN::Client->ls to
fetch all items in a certain level.

For each item I can get the last mod time:

> =item $dirent-E<gt>time()
>
> Time of created_rev (mod-time).

This yields me roughly:

> 1125338412570734

The first half of that looks like seconds-since-epoch time:

> 1125594190

So what's tha rest of that data?
