Hi Maxim, I'm not saying that we should use this JS library. I just saw it and decided to share it with you so that you can see whether it will help you anyhow.
Also I've noticed that Wicket already has code for detecting the time zone. See org.apache.wicket.protocol.http.ClientProperties#getTimeZone http://www.wicket-library.com/wicket-examples-6.0.x/ajaxhellobrowser/ for me shows: Based on your settings, your time is: 1:16:44 AM PST (and your time zone is Central European Time) The time is not what I'd expect, it should be 10:16:44 AM CET instead. The timezone (CET) is correct though. But I guess you want to see something like Europe/Moskow ? I.e. the time zone identifier. For this you will need the locale too. P.S. Running wicket-examples locally gives correct results. So it could be that wicket-library.com runs with wrong clock ?!
