@Calin, you can use (new Date().getTimezoneOffset() / -60);
Then you can use code like this
http://examples8x.wicket.apache.org/ajaxhellobrowser/wicket/bookmarkable/org.apache.wicket.examples.source.SourcesPage;jsessionid=01612235C0920A71B39B2D8CA0FA641A?0&SourcesPage_class=org.apache.wicket.examples.ajaxhellobrowser.AjaxHelloBrowser&source=AjaxHelloBrowser.java
to get this value on the server side
@Martin Actually the code works, BUT
1) for me it shows timezone as "GMT+07:00" instead of Asia/Novosibirsk
And there are a lot of time zones with same offset ....
2) there are a lot of magic in the current code (for ex.
southern hemisphere time zone calculation
https://issues.apache.org/jira/browse/WICKET-6689)
3*) I guess this calculation can stop working in a year time zone rules are
changed
I believe this might be improvement to wicket code base to let browser do
the real time zone calculation :)
