OK, I got curious and looked at it a little. It works by adding the extra form values to the $timezoneoptions variable, so as long as you have that in your style it should be OK.

But I was only guessing that that was the problem, it could be something else.

Edit: OK, Chadi, I looked at your site and I see that the mobile style doesn't have the option to select the timezone, so I guess that's the problem. RIght now it doesn't look like there's any way to add it manually because I'd have to register the variables to your template. But I can add an option to do that (and maybe it will solve some other people's problems as well).
