A generic would probably work. To be honest, I am not sure of the need of
accuracy, but you know every time we try to generalize it tends to come back
on us.
Also, as a side note, I realize now that is not a hyphen before the off-set.
That is a -4 hours which was the GMT off-set of my test data. That could
just as easily be +02:00 if my data was the other direction of GMT. Not
that it matters to the issue, but a clarification of the data syntax.

So, my dilemma is this - based upon a specific date and time, in a
specific city/state, how can I compute the number of hours difference
to GMT for that moment?
I don't know of a public database of city, date, UTC offset. Because that's
what is needed for a generic solution to this problem. Because the date of
the switch between summer and winter time has changed through the years due
to legislation.
Perhaps a universal, generic solution is overkill for the immediate problem?
