I suppose you could also modify one of the GnomeDbEntryDate for dates
(or GnomeDbEntryTime for time, ...) for example to add some format
specification, and then one could set that format as with any other
plugin (exactly in the same way). This could also be applied to the
GnomeDbEntryString (for numbers and strings).

As a matter of fact I was planning to add a way to specify a mask to
enter data (as for example like
http://gtkmaskedentry.sourceforge.net/), and other attributes such as
text max length; so if you can wait till next week (I probably won't
have the time to do it before), you'll have the framework in place to
add more format spec.
