Hi Derrell,

I'm using Firefox Version 3.6.3

My idea for a workaround is that the RpcJava backend can take care of
the problem while serialization and de-serialization the date objects.
I'll have a look at it, maybe I'm able to provide such a workaround.

Regards,
Andreas

Hi,

I've digged deeper in the problem and found out that the daylight saving
offset is handled different in Java and Javascript.
For example:
The date 04/01/1980 is in javascript handled with a daylight saving
offset and in Java without the offset.
(In the year 1980 the daylight saving hour was added on the first Sunday
in April. Javascript add the hour at the last Sunday in March...)

Java does a quite good job compared to the official rules you can find
here (in German):
http://de.wikipedia.org/wiki/Sommerzeit#Deutschland

Javascript only uses the last official daylight saving rule and not the
really used rules.
That's really hard to handle.

That's almost certainly JavaScript-implementation specific. 

It is, actually, a very difficult job to keep up with daylight savings
time rules. They change throughout the world on a much more frequent
basis than one would think. There are regular updates to the Linux
package that handles such things... and much less frequent updates to
some browsers.

What browser and browser version are you using?
