Hi, actually subtracting Date.getTimezoneOffset() was the only reliable cross-platform way that we found. The trick is to set the server timezone to GMT with the appropriate java command line option that I don’t remember right now… For presenting the dates on the client we also use the same approach as you.

Hi Olivier,
I was wondering what was the operation you’ve made in order to sync Date instances generated in the client browser (in ant timezone) and the Dates on the server. Subtracting the Date.getTimezoneOffset by the Date.getTime can make things really messy (at least if you’re using GXTs DateField).

Also, for presenting the Dates coming from the server I’m currently using the DateTimeFormat with a specific TimeZone created in the client side. Looks ok so far. Is that you’re approach as well?

cheers!

Yeah, that’d be awesome. If you have any feedback feel free to contact me, my email address is on the project page.

This is great! I haven’t tested it extensively but it looks good so far… I hope you don’t mind that I tweeted about it

Take a look at http://code.google.com/p/gwt-calendar-class/ . I’ve started porting java.util.Calendar, java.util.TimeZone, and java.util.Locale to GWT. It’s not a full implementation but it handles most of the basic use cases of Calendar.

DateJs looks nice, but I’m not sure it solves the same problem.
Let me know how it goes!

Just stumbled upon to a GWT project, which has a DateJs wrapper.

Going to use it, or atleast try it in our project.

Hi, I stumbled across this article because I was having the exact same problem.. the fact that GWT doesn’t have a proper solution for this is ridiculous, but I did try the datejs library and as far as I can tell it does work very well!
As Zack said, just include the js file in your application and then use it via native JavaScript (JSNI) methods.
Glad I found this post!
