Changes in tzdata2007g:
* Egypt switches the September 7, not September 28.
* 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.
