This is probably a patch/DST issue, so if anyone could confirm, that would
be great.

If I had an appt. to my handheld toward the end of March and do a sync, it
comes into my GroupWise calendar an hour later. If I modify my GW appt. to
be an hour earlier and do another sync, it changes my handheld up one hour
(so it is now an hour early).

Sounds very much like a DST issue to me, but I wanted to make sure the GMS
patch was going to resolve this issue.
