Are there a countable number of places that observations are done in? Are
the differences at all predictable?

What happens when it's wrong; presumably we want to correct this ASAP, so
it should be easily replacable.

/me imagines NTP servers with an extension... :)

That'd be very interesting, but would require glib knowing your latitude,
longitude, altitude, whether there are mountains, and probably some other
things.

I'm going to do an initial patch for a few more simple calendars.
(Gregorian, Julian, Persian, and probably some interesting proposed reform
