I am trying to send UTC time-stamp to rest service from my javascript client. i was not able to create time-stamp like "2013-08-30T19:52:28.226Z" using javascript.

var rawDate = date.getUTCDate().toString();

Answer 1

You can use date.toJSON().

new Date().toJSON()
"2013-08-31T09:05:07.740Z"

See MDN or MSDN

Answer 2

1) Get the date.

var now = new Date();

2) Convert to UTC format like below, for reference.

var now_utc = new Date(now.getUTCFullYear(), now.getUTCMonth(), now.getUTCDate(), 
                  now.getUTCHours(), now.getUTCMinutes(), now.getUTCSeconds());

3) Using toJSON, get the format.

now_utc.toJSON()

Finally,

var now = new Date();
var now_utc = new Date(now.getUTCFullYear(), now.getUTCMonth(), now.getUTCDate(),  now.getUTCHours(), now.getUTCMinutes(), now.getUTCSeconds());
alert(now_utc.toJSON());
