Convert system date to ISO format using momentjs

Question

I'm trying to convert system date to ISO format in below fashion using momentjs

2015-02-17T19:05:00.000Z 

I'm however unable to find the parameter that I need to use to get it in the format which I want. I tried below piece of code..

moment().format("YYYY-MM-DD HH:mm Z");

I get output as 2015-02-02 17:24+05:30.

How can I get it as 2015-02-02T17:24:00.000Z

This is pretty well covered in the docs . But, they're long, so here's the specifics:

For some reason, momentjs's definition of ISO 8601 differs from the ECMAScript one, so it isn't built in. The format is YYYY-MM-DDTHH:mm:ss.sssZ and it must be in UTC (the Z denotes this).

So, moment().utc() makes sure the timezone is correct.

Then format it:

moment().utc().format("YYYY-MM-DDTHH:mm:ss.SSS[Z]");
// 2015-02-02T21:38:04.092Z

The Z is escaped with square brackets . We can do this safely because we forced UTC.

The rest of the characters denote various time elements according to the format table .

You could also do what RobG said and use the native date object. In case you are starting with a moment:

moment().toDate().toISOString( )
// 2015-02-02T21:40:06.395Z
