I've been thinking about this and although I think I have a general idea how to 
do it, I don't think that I want to. You see, I don't want my decision to 
depend on the date field of the database. That could change for all sorts of 
reasons - copying, downloading, HotSyncing, beaming - heck, it can even be 
changed with third-party utilities like Filez.

No, I want my decision to depend on some piece of data *inside* the database; a 
record that contains the creation date and that is put there by the database 
compiler, that isn't changed by anything, and that if somebody tries to muck 
with it, I'll detect the change during the integrity check of the database's 
contents.
