Hi,

I'm just going into some trouble after we'd deployed/tested the application (with Ext JS 4) on a server not in the same time zone than the clients.

Originally, the date/timestamps are served in the ISO format with timezone:
PHP Code:
// Property of record serverside
datetime : "2012-10-18T16:17:51.299+0200" 
Since Ext JS 3, we've used the model type "date" + dateFormat "c". If I'm correct this dateFormat wont be supported??
Removing the dateFormat (only type "date") works in Chrome/Firefox perfectly (because of internal JS' Date usage), but not in IE (NaN/empty grids).

Because of this issues, I've revisited the doc.. and there are some examples.

I changed the timezone of my VM to Hawaii and use a my-local timezone (Germany).

Using the library with a example string right of the documentation:
Ext.Date.parse("1997-05-16T19:23:30.12345+02:00", "c").toString()

should not be
Fri May 16 1997 19:23:30 GMT-1000 (Hawaii Normalzeit)

but should be
Fri May 16 1997 07:23:30 GMT-1000 (Hawaii Normalzeit).

In Chrome (native)
new Date("1997-05-16T19:23:30.12345+02:00")

is okay. In IE, this is NaN.


edit: Anyway, I've open a ticket.

You break down the whole issue with following one-liner:
Ext.Date.parse("2012-10-18T16:17:51.299+0000", "c")


This date should be the 18th Oct 2012, 16h17m51s (UTC) because timezone 0.


In my case, the local timezone is +0200. So, when using the line above in Ext JS 4.1.1
Thu Oct 18 2012 16:17:51 GMT+0200 (CEST)


But in Ext JS 4.1.2
Thu Oct 18 2012 18:17:51 GMT+0200 (CEST)




I tried it again, the same expression with the timezone Hawaii set up in the operating system.
In Ext JS 4.1.1
Thu Oct 18 2012 06:17:51 GMT-1000 (Hawaii Normalzeit)


But in Ext JS 4.1.2
Thu Oct 18 2012 16:17:51 GMT-1000 (Hawaii Normalzeit)
