Set default TimeZone of the browser window in javascript
===

We are displaying schedules on our webpage which is build on GWT. Client system using different timezone from server and because of that, all the schedules were displaying wrong. Is there a way to set default time zone when we load the page? Like the way we do it in java: 

TimeZone.setDefault(TimeZone.getTimeZone("Asia/Kolkata"));

Thanks!!!
