DatePicker UTC

[Thomas Lefort]

I need the datepicker to render the date in UTC and not the local
format. Is there any simple way to do so?

To be more clear, I have a date which is 2012-03-29 at 01:00:00 UTC, if I do setDate(date) on the datepicker and if the user is based in the US, the date selected on the calendar will be the 2012-03-28, because it uses their local time. I want the calendar to show 2012-03-29 wherever the user is.

I created one based off of this for GXT and this should do what you want.  Although when I went to create a GXT version, I kept it so get/setValue used Date and not Long but did the timezone offset subtraction that this did.

Just saw your answer, thanks.

I use JsDate to get the UTC conversion. However this still doesn't work for the picker, as it will still display the date using the local time format. If I have 12/04/2012 at 1am UTC in the US, it will show me the picker at 11/04/2012. May be the solution would be to pass a "converted" date to the picker, ie add the time offset to the data when opening the picker. I do not use the DateBox but my own widget, so I can pass the date I want to the picker.
