I have been searching and cannot find a way to determine the time
between two date/time/zones as shown below. Does anyone have a
routine that can do this easily without having to manually convert
everything to gmt? Thanks.

You picked two "simple" time zones. Will it always be those two? If not,
you're better off using a library routine to convert them to UTC for
arithemetic, as time zones can get very strange. Daylight Saving Time will
make it very complicated when you're near a DST transition.

This is what I am afraid of. It could be any time zone. Do you
know of a
library routine that does this?

Will datediff not handle this directly (I haven't tried it)? If not,
then it should work if you convert them to GMT first, and then use
Datediff on those values.
