Did you stop and restart PM Mail each side of the change over time? It 
doesn't pickup any change until it is stopped and restarted.

It does look like it has gone a day early. Someone has already pointed 
out the very useful utility TZCalc, it's probably on hobbes in 
/pub/os2/util/system. This will verify that you have the correct TZ 
enviroment string set. BTW, do not trust the built in zones, it gets the 
UK wrong. It calls our winter time "BST" should be "GMT" (Greenwhich 
Mean Time) and our summer time "BDT" should be "BST" (British Summer 
Time). I think the times of transistion are wrong as well but don't 
quote me on that.

It is far better to plug your own, known to be correct, values into it 
and get the string thus generated.

Yes. GMT is GMT it does not move. In fact one could argue that no time 
(GMT, BST, EST etc) moves it's just that us humans hop use a different 
one at different times of year.

If we knew what it was we might be able to comment. It is normal for the 
transition to happen in the early hours of a Sunday morning.
