Convert current time to milliseconds using moment

Suppose I have this time

'2018-08-03T15:53:57.000Z'

I need to convert only the time part to milliseconds

I tried this but didn't work and throws error

moment.utc("2018-08-03T15:53:57.000Z").format('HH:mm:ss').milliseconds()

Error

TypeError: (0 , _moment2.default)(...).format(...).milliseconds is not a function

Can someone please help how can I convert only time to millisecond?

Thank you!!!

Welcome to Stack Overflow. Would you like milliseconds from 00:00 local user time to 15:53:57.000 UTC or 00:00 to 15:53:57.000 local user time?

So the Z in 15:53:57.000Z is not used at all? If you do new Date('2018-08-03T15:53:57.000Z') you'll likely get a different time unless you happen to be in the UK.

No need to use moment to do this. The date string can be parsed sufficiently by vanilla JS.

var date = new Date('2018-08-03T15:53:57.000Z');

And to get the timestamp (in milliseconds) of this date;

var millis = date.getTime();

And, since there are 86400 seconds in a day (24*60*60) there are 86,400,000 milliseconds and we can use the remainder after divission by this number to get the number of milliseconds the time portion represents.

var millisToday = millis % 8640000;

UPDATE

Now using getTime() instead of valueOf() as it is the "proper" way to get the timestamp of the Date object.

I'll add my answer in case I got it wrong then someone can comment.

If I send new Date().toISOString() to someone in a different time zone then the time will differ for this person. If I ask that person to have a skype call at 13:00 their time it could mean it's 18:00 my local time.

So if the person sending me the date string is from the UK and sends me ...T13:00.000Z That actually means 18:00 for me.

Here is how you can correctly get the time in milliseconds from your midnight of the date converted to your local time:

const date = new Date(2007, 1, 1, 0, 0, 2).toISOString();

console.log('date:',date);

console.log('date in your local time:',new Date(date).toString());

const millisecondsFromMidNight = (date) => {

  var dateObject = new Date(date);

  return (

    dateObject.getTime() -

    new Date(

      dateObject.getFullYear(),

      dateObject.getMonth(),

      dateObject.getDate(),

      0,

      0,

      0,

      0,

    ).getTime()

  );

};

console.log(millisecondsFromMidNight(date));

Example where DST goes in effect:

var minutesFromMidnight = (date) => {

  var dateObject = new Date(date);

  console.log('date:', date);

  console.log(

    'date in your local time:',

    dateObject.toString(),

  );

  return (

    dateObject.getTime() -

    new Date(

      dateObject.getFullYear(),

      dateObject.getMonth(),

      dateObject.getDate(),

      0,

      0,

      0,

      0,

    ).getTime()

  );

};



console.log(

  minutesFromMidnight('2018-10-28T00:59:00.000Z') / 60000,

);

console.log(

  minutesFromMidnight('2018-10-28T01:01:00.000Z') / 60000,

);

This will likely fail if there is a change in daylight savings on the date in question. e.g. in the UK, on 25 March 2018 at 01:00 daylight savings began so the time is then 2018-03-25T02:00:00+01:00 but midnight was 2018-03-25T00:00:00+00:00. Although it is only one hour since midnight, i believe your answer will count 2. Don't know if that's a level of detail beyond what OP wants though!

console.log(

console.log(

This will likely fail if there is a change in daylight savings on the date in question. e.g. in the UK, on 25 March 2018 at 01:00 daylight savings began so the time is then 2018-03-25T02:00:00+01:00 but midnight was 2018-03-25T00:00:00+00:00. Although it is only one hour since midnight, i believe your answer will count 2. Don't know if that's a level of detail beyond what OP wants though!

@phuzi I have added an example minutes from midnight with one value in DST and one 2 minutes later out of DST (western Europe) and it works correctly.

@Profer It is if you're in the UK and not currently in DST.

I'll add my answer in case I got it wrong then someone can comment.

So if the person sending me the date string is from the UK and sends me ...T13:00.000Z That actually means 18:00 for me.

Here is how you can correctly get the time in milliseconds from your midnight of the date converted to your local time:

const date = new Date(2007, 1, 1, 0, 0, 2).toISOString();

console.log('date:',date);

console.log('date in your local time:',new Date(date).toString());

const millisecondsFromMidNight = (date) => {

  var dateObject = new Date(date);

  return (

    dateObject.getTime() -

    new Date(

      dateObject.getFullYear(),

      dateObject.getMonth(),

      dateObject.getDate(),

      0,

      0,

      0,

      0,

    ).getTime()

  );

};

console.log(millisecondsFromMidNight(date));

Example where DST goes in effect:

var minutesFromMidnight = (date) => {

  var dateObject = new Date(date);

  console.log('date:', date);

  console.log(

    'date in your local time:',

    dateObject.toString(),

  );

  return (

    dateObject.getTime() -

    new Date(

      dateObject.getFullYear(),

      dateObject.getMonth(),

      dateObject.getDate(),

      0,

      0,

      0,

      0,

    ).getTime()

  );

};



console.log(

  minutesFromMidnight('2018-10-28T00:59:00.000Z') / 60000,

);

console.log(

  minutesFromMidnight('2018-10-28T01:01:00.000Z') / 60000,
