From Paul Eggert's comments:
* Egypt switches the September 7, not September 28. Thanks to Dirk
Losch for this.
* Daviess, Dubous, Knox, Martin, and Pike Counties, Indiana, switch
from central to eastern time in November. This results in a zone
split, and a new entry America/Tell_City is created for Perry County,
which does not switch zones in November.
* South Australia, Tasmania, Victoria, and New South Wales are changing
their DST rules effective next year. DST will end the first Sunday in
April at 03:00 and start the first Sunday in October at 03:00. Lord Howe
Island has a similar change.
* Several Antarctic station's rules weren't properly updated to account
for this year's change to the New Zealand daylight saving rules.
* In zone.tab (sorry, I don't recall who sent in these changes):
** Dumont-d'Urville is a station, not a base.
** Correct the coordinates for Aruba, Cambridge Bay, London, Johnston.
** Give alternate spellings for Zaporozhye.
* Add spelling notes for Kiev, Uzhgorod, Zaporozhye.
(Sorry, I forgot who wrote this.)
* Identify American time zone boundaries more carefully.
(Sorry, I forgot who sent this in.)
* Improve historical notes for Howland, Baker, and Jarvis.
Additionally, this commit updates the "leapseconds" file to incorporate the
most recent International Earth Rotation and Reference Systems Service (IERS)
bulletin.
