Here's an updated proposed change, reflecting the information from Steffen
Thorsen. The "asia" differences are against the current ftpable version.
We'll need to revisit Bangladesh once the 2009 end date is determined.
I've also added Eric Muller's tz-link.htm update.

Barring problems, these will show up in the ftpable version on 2009-06-08.
