How to format date and time like this in JavaScript ?

March 05, 2012 @ 14:30 (UTC - 9:30)

I use this code to calculate EST time :

function getDate() {
    var now = new Date();
  var  utc = now.getTime() + (now.getTimezoneOffset() * 60000);

    return new Date(utc + (3600000 * -4));
}

I use the date-time-format that Tats remended because doing it manually is a huge PIA.

var yourDate = dateFormat(getDate(), "mmmm dd, yyyy @ HH:MM) + "(UTC -9:30)";

Keep in mind this isn't Daylight Savings aware.. and you are asking for UTC -9:30 in your format, but your function converts to -4. Also, I believe that now.getTime returns in UTC.. so you can just add your difference there.

JavaScript Date Format

Check out date.js! It's a really powerful little library for working with Dates in JavaScript.

To get today's date in EST, you can do something like...

var today = new Date();
today.toString();         // outputs "Wed Apr 11 2012 15:40:40 GMT-0500 (CDT)"


today.setTimezone("EST");
today.toString();         // outputs "Wed Apr 11 2012 14:40:40 GMT-0500 (CDT)"

Also, its worth mentioning to checkout moment.js. I think the two libraries plement each other.

If you do just

var now = new Date();
document.write(now);

you will get

Wed Mar 14 2012 20:53:06 GMT+0000 (GMT Standard Time)

Link1, Link2.

Is it what you want?
