How to get todays date in the same format as an existing date?

Question

I'm trying to get todays date in the same format as my variable. The variable outputs the below:

2016-05-18T23:00:00.000Z

Where as this code below outputs the below:

1463152286532

 Date.now()

So the question is what do I have to do to Date.now() to make it the same format as my first blockquote.

Answer 1

The format you've shown at the top is the standard "ISO" format returned by Date#toISOString (spec | MDN). So:

new Date().toISOString();

Note: Date.now() returns a number, not a Date. It's the number of milliseconds since The Epoch (Jan 1st, 1970 at midnight UTC).
