Subj : Daylight saving time problem (maybe)

I'm trying to find out why messages I create in Thunderbird and events I 
create in Sunbird have the wrong time on them.  It seems to be because 
JavaScript is ignoring DST.

For example, as I write this it is around 13:45 local time in the UK. 
That's 12:45 UTC, because the zone offset here is +0000 and DST is 
currently in effect.

In Mozilla 1.8a3 on Windows 98, I type:

   javascript: with (new Date()) getHours() + " " + getUTCHours()

I see the result:

   12 12

where the first number, the hour in local time, is wrong.

But if I type:

   javascript: with (java.util.Calendar) getInstance().get(HOUR_OF_DAY)

I see the correct hour in local time:

   13

If I set my machine for New York time it is around 8:45 a.m. EDT (still 
12:45 UTC, of course).  JavaScript returns 7 12, where the 7 is wrong, 
and Java returns 8.

Am I right in thinking that these numbers are wrong?  Is there some 
setting that I can tweak to fix things?
