    @Guruparan - not a very clear question to answer this one with - I would think >[this one](http://stackoverflow.com/questions/10087819/convert-date-to-another-timezone-in-javascript)< more appropriate – mplungjan Apr 16 '12 at 06:11

I think you can use timezone-js.

Create a timezoneJS.Date the same way as a normal JavaScript Date, but append a timezone parameter on the end:

var dt = new timezoneJS.Date('10/31/2008',
  'America/New_York');
var dt = new timezoneJS.Date(2008, 9, 31, 11, 45,
  'America/Los_Angeles');

OR

you can approach like this:-

var now = new Date();

var utc = new Date(Date.UTC(
    now.getFullYear(),
    now.getMonth(),
    now.getDate(),
    now.getHours(),
    now.getMinutes()
));

Now for different timezone you need to add or subtract the time by which they differ from GMT.
Note :-Date.UTC() returns the number of milliseconds since the epoch, UTC.

    take the date from user but parse it in a proper format . you can search on SO, for lot of answers about how to parse a date format – Pranav Apr 16 '12 at 06:33
