datetime stamp on db.xml

[nix4]

I'm working on parsing the db.xml file in order to display some data on my campaign web site regarding character stats (name, class, level).

I came to notice that the character data thats stored in db.xml dosnt have a datetime stamp of its last update.

I would like to throw in my 2cp for a datetime stamp indicating the last time the record sheet was updated or used. That way automated systems or manual editing would allow for removal of old data.

Thanks!
