Format date time in gwt with timezone

I am need to format a date and display it to users based on users location.

I am trying to format the time using the following code

DateTimeFormat.getFormat("h:mm a z").format(new Date(timeInMillis))

This is the result i am getting "5:18 PM UTC-4" for new york users and "2:18 PM UTC-7" for seattle users. How do i generate string like "5:18 PM EST" for new york users and "2:18 PM PDT" for seattle users?

Note: the problem with using format(new Date(time), timezone) is that how to create a timezone object based on user locale? Timezone.createTimeZone(int) gives SimpleTimeZone implementation which will produce "UTC-4", in-order to generate "PDT", timezone has to be created with Timezone.createTimeZone(timezoneJson: string) but issue in this is that we have to pick the timezone at the compile time to create the input timezone json string.

Thanks in advance

You need to pass a TimeZone object to the formatter:

format.format(new Date(), timeZone));

Note that the best way to create TimeZone is from a JSON string that contains information on changes to time zone in the past. If you app does not deal with time in the past, then this may not be necessary.
