I\'m a Java developer and I\'m used to the SimpleDateFormat class that allows me to format any date to any format by settings a timezone.
Date date = new Dat
This is an old question, but since I found it:
As mentioned, there's nothing reasonable built-in.
As for libs, there is Moment Timezone for Moment.js.
Here is a JSfiddle with an example: http://jsfiddle.net/kunycrkb/
The same code inline:
var m = moment("2014-06-01T13:05:00Z");
var f = "HH:mm z";
$("#results").text(m.tz("UTC").format(f) + " is " + m.tz("EST").format(f) + "!");
