Supporting any type of customization of this widget (either providing an alternative or having settings for this one) requires that something keep track of that configuration, which means you're back in the server/account business again.
The stub server is *very* simple, since it was basically an emergency life-support system - it doesn't really keep track of anything (well, to be fair it keeps track of some analytics, but that's about it).
The full server, which is being tested now, supports the bulk of the original service, in which case this sort of customization would be possible.
In the case of that widget, I *think* it understands the 12/24 hour flag that some of the Control Panels support, but I don't know if the entire font is included, or if that font has all the necessary characters to support a rich set of translations.
