My client wants to have a calendar picker with support for time zones. Right now they are using the venerable calendar_date_select picker
http://code.google.com/p/calendardateselect/
Which has no support for time zones. Surprisingly, I can't find any other plugins or other help in handling this. I would think this was a common problem - e.g. someone in Chicago wants to enter a time in Tokyo. This seems like a reasonable thing to want, but it also seems like it's a lot harder than it ought to be.
The only thing I've found that looks even vaguely promising is the any+time picker:
But (a) I'm not convinced that will play nicely with Rails and (b) I can't use jQuery. Has to be Prototype. Don't ask.
Is there something I'm missing here? Is there a Rails-friendly date/time picker with time zones out there? It looks like I'll have to make some fairly extensive modifications to calendar_date_select if there isn't. Any tips on how to keep time zones working sensibly across rails/javascript?
