I think that if we calculate/read the message's GMT hour, we can only
be off by 0 hours, + 24 hours, or -24 hours, because GMT is GMT no
matter which side of the International Date Line the message was sent
from. I infer that there are only twelve (a very finite number) of
possible offsets:
EDT: -4, -28,
-4+24=+20, -28+24=-4
-4-24=-28, -28-24=-52
EST: -5, -29,
-5+24=+19, -29+24=-5
-5-24=-29, -29-24=-53
I can modify TZSelect to check for twelve (rather than four) offsets,
if you think it necessary.
===========================
It occurs to me that Windows knows what time zone my clock thinks it's
in, and Windows knows (or has calculated) whether to keep Daylight or
Standard Time. Can Window's brain be picked?
What do you think?
