From Paul Eggert's comments:
* Changes affecting future time stamps.
- The Bahamas also observe the new US DST rules this year.
(Thanks to Sue Williams for this.)
* Changes affecting TZ names, to reflect typical English practice better.
The old names are still supported, in the 'backward' file.
- Rename Africa/Asmera to Africa/Asmara.
- Rename Atlantic/Faeroe to Atlantic/Faroe.
* A new zone Australia/Eucla, covering the Eucla area. (Thanks to
Alex Livingston for this.)
* Changes affecting old time stamps.
- The 1982 transition for Pacific/Easter occurred Mar 13, not Jan 18.
Also, the pre-1932 time stamps are now labeled EMT, not MMT, since
they are not Mataveri Mean Time. (Thanks to Jesper Norgaard Welen
for this.)
