Take a look at this article: https://web.archive.org/web/1/http://articles.techrepublic%2ecom%2ecom/5100-10878_11-6016329.html

Lifted straight out from that:

 function calcTime(city, offset) {

// create Date object for current location
d = new Date();

// convert to msec
// add local time zone offset
// get UTC time in msec
utc = d.getTime() + (d.getTimezoneOffset() * 60000);

// create new Date object for different city
// using supplied offset
nd = new Date(utc + (3600000*offset));

// return time as a string
return "The local time in " + city + " is " + nd.toLocaleString();

 }

Call it like: alert(calcTime('Bombay', '+5.5')); // get Bombay time

You may need to add a bit of logic to take into account daylight saving time.
