How to set 00:00:00 using moment.js [duplicate]

I want to get current date but time should be 00:00:00.000

I've try this:

var m = moment();
m.set({hour:0,minute:0,second:0,millisecond:0});
console.log(m.toISOString());

but I've got: 2016-01-12T23:00:00.000Z why 23 and not 00?

Moment.js stores dates it utc and can apply different timezones to it. By default it applies your local timezone. If you want to set time on utc date time you need to specify utc timezone.

Try the following code:

var m = moment().utcOffset(0);
m.set({hour:0,minute:0,second:0,millisecond:0})
m.toISOString()
m.format()

var time = moment().toDate();  // This will return a copy of the Date that the moment uses

time.setHours(0);
time.setMinutes(0);
time.setSeconds(0);
time.setMilliseconds(0);
