Can anyone tell me if there is a fix for the fix?

I have the fixes for the US DST problem, but for recurring meetings that
were schedule before the fixes when out, they are actually incorrect for a
three week period (March 11 through April 1).

I've tested new requests, and they all see to work fine, but the old ones
are all off by one hour.  I can't live with some meeting being correct on my
calendar and some being wrong for three weeks.

Here is my specific problem, my US based manager has a recurring meeting on
my calendar (I'm in Germany) every Tuesday at 14:00 my time.  This is her
meeting request, so I would expect it to move to 1 hour earlier on the weeks
of March 11 and 18, but it still shows in my calendar at the same time.  On
top of this, for the week of March 25, it shows as one hour later.  All three
of these are incorrect.

Help!
