Hi John,

First it killed my dog then it screw up my television set ...
No, the only problem is that it print outs incorrect results. ;-)
Code is quite simple:
Date date = new Date();
System.out.println(myFormatter.format(date));
On my machine, it gives me the correct time,
on the other machine, it gives me correct time + one hour.
I assume that Java ignores this one flag ("change according to
daylight saving times automatically") that you can setup in
Windows Date settings.
If I switch of this feature on my machine, the Windows clock will
show me "correct time - one hour". I assume that Java always takes this
time and adds one hour. Correct for my machine, but not correct
if you switch off the windows flag and tell your machine the exact time
(meaning: the user changes the clock if daylight saving time changes - and not
the system).
Maybe a table makes it more clear:
actual time windows time (internal) windows external Java
my machine 10:00 9:00 9 + 1 -> 10:00 9+1-> 10:00
customer 10:00 10:00 10 + 0 -> 10:00 10+1 -> 11.00
