subtract time from date - moment js

rated 0 times [ 65] [ 4] / answers: 1 / hits: 174075 / 10 Years ago, thu, june 26, 2014, 12:00:00

I have for instance this datetime:

01:20:00 06-26-2014

and I want to subtract a time like this:

00:03:15

after that I'd like to format the result like this:

3 hours and 15 minutes earlier.

How can I do that using moment.js ?

edit: I tried:

var time = moment( 00:03:15 );

var date = moment( 2014-06-07 09:22:06 );



date.subtract (time);

but the result is the same as date

Thanks

Moment.subtract does not support an argument of type Moment - documentation:

moment().subtract(String, Number);

moment().subtract(Number, String); // 2.0.0

moment().subtract(String, String); // 2.7.0

moment().subtract(Duration); // 1.6.0

moment().subtract(Object);

The simplest solution is to specify the time delta as an object:

// Assumes string is hh:mm:ss

var myString = 03:15:00,

    myStringParts = myString.split(':'),

    hourDelta: +myStringParts[0],

    minuteDelta: +myStringParts[1];





date.subtract({ hours: hourDelta, minutes: minuteDelta});

date.toString()

// -> Sat Jun 07 2014 06:07:06 GMT+0100
