Re: add timer on panel......
If I recall correctly, System.currentTimeMillis() still works in GWT. In your timer code, this can be called; end_time + start_time - current_time will give you how much time is left.

Re: add timer on panel......
Harshal, You will need to write a simple stopwatch state machine. You can wrap it up as a simple widget to display the time. Basically you just need to track the current time and decrement it every second. This has been discussed before on StackOverflow herehttp://stackoverflow.com/questions/6725365/countdown-clock-in-gwt. See the use the GWT Timer in the bottom answer. You'll also want to have some functions to convert seconds to formatted time to display it in your widget. You could use some GWT formatters on the Date object, or just write your own functions since the math is simple. You'll want to check on the start time/ elapsed time on the server side too since a mildly talented use could hack the browser side timer. The possible trouble point here is that there is no guarantee that your timer and the serverside will match, since JS could lose time if there was contention for the browser thread, and neither side is an RTC. The last thing you'd want is for someone to finish in time, but get rejected by the server when submitted because they were overtime.
