Not sure here, but doesnt the JDK take care of the daylight savings in a
specific timezone by itself?
GMT+1 should be static shouldn´t it?

AW: t:inputCalendar f:convertDateTime DaylightSaving

[Holger Igel <ho...@cosys.de>]

Yes the JDK handles the daylight saving. I found the solution. You have to
use a TimeZone ID like 
Europe/Amsterdam
Europe/Andorra
Europe/Belgrade
Europe/Berlin

Java.util.TimeZone

String ids[] = TimeZone.getAvailableIDs();
		for (int i = 0; i < ids.length; i++) {
			log.debug(ids[i]);
		}

My mistake was to take GMT+1 or GMT+2.
If we are in daylight saving time we have GMT+2 else GMT+1.
If I use 
<f:convertDateTime type="both" dateStyle="medium" timeZone="Europe/Berlin"/>

It works fine !

Hello,

Yes, the JDK take care of that. However, there's some potential problems
like you need close to latest JVM to include this year changes on daylight
saving, and there's also an issue with a very specific date around 1930 that
I forgot which is very buggy (selecting the day before)...
