What is the JavaScript equivalent to the following PHP code:
$expTime = time() + (5 * 60 * 60); // now plus 5 hours (5 hour; 60 mins; 60 secs)
$expTimeStr = gmdate('Y-m-d\TH:i:s\Z', $expTime);

var expTime = new Date((+new Date()) + (5 * 60 * 60000))
var m = expTime.getMonth() + 1
var d = expTime.getDate()
var y = expTime.getFullYear()
var h = expTime.getHours()
var i = expTime.getMinutes()
var s = expTime.getSeconds()
var expTimeStr = y +"-"+ m +"-"+ d +" "+ h +":"+ i +":"+ s

This isn't going to work. If the time is 11:00PM, then the hour will be correct, but the day display will be wrong.

fixed bluntly using gnarfs method for the +5 hours

That's a nice solution! I changed something anyways: it's weird that you don't have a leading zero for Month, Day, Minutes and Seconds (even Hours). So, to whom might be interested:
var expTimeStr = y +"-"+ (m.toString().length<2 ? '0' : '')+m +"-"+ (d.toString().length<2 ? '0' : '')+d + ...pmrotule
Important!! If you want the right local time offset:
var expTime = new Date((+new Date()) + (new Date().getTimezoneOffset() * 60000))The gmdate() function doesn't transfer well to JavaScript... There is a gmdate() port on phpjs that uses the date() function from phpjs to do the complex formatting.
To calculate the date:
var time = new Date((+new Date()) + (5 * 60 * 60000)); // js times are ms
alert(time.toUTCString()); // quick JS method to return UTC time
The (+new Date()) forces the Date() into an integer before adding ms, and passing it back to the new Date() constructor.

The built in date formatting for Javascript isn't incredible, but I can offer two helpful libraries to accomplish what you want. The first is something called phpjs - Javascript ports of a number of php functions.
http://phpjs.org/functions/index
http://phpjs.org/functions/gmdate:586
The second is a jQuery plugin:
