[tz] US Sep 30, 1945

[Ken Murchison]

All,

I'm wondering why the US rule for Sep 30, 1945 uses an explicit date 
rather than lastSun, where it would dovetail nicely into the existing 
rules for America/New_York, Chicago, Indiana/Indianapolis (and maybe 
others) which cover 1946-1954.

The only reason that I care is because when converting the TZ data into 
iCalendar VTIMEZONEs with vzic, the dst->std transition for 1945 doesn't 
get coalesced into the recurrence rule for 1946-1954. I won't bother 
going into the reason for how/why vzic isn't able to coalesce these, but 
I'm pretty sure that it would take a non-trivial amount of 
work/logic/code to fix it.
