Description

So you can easily see when the FSMap epoch was published (real time) without looking at each file system's mdsmap. In fact, none of the file system's mdsmaps may be updated if e.g. only a standby was added.

Add tests to confirm that the time is added to the FSMap and that it's accurate.
