AngularJS: How to print out duration time with format?

Question

I use below code to print the time duration:

{{(endTime - startTime) * 1000 | date: 'H:mm:ss'}}

But I get the time of GMT +8

AngularJS has any way to print out the non-convert duaration, Or I need to use this way to do this?

{{(endTime - startTime) % (60 * 60 * 24) / (60 * 60) | number: 0}}:
{{(endTime - startTime) % (60 * 60) / 60 | number: 0}}:
{{(endTime - startTime) % 60 | number: 0}}

Answer 1

In AngularJS 1.3 and up, there is optional timezone argument in date filter. The doc says If the timezone is not specified, the timezone of the browser will be used.

https://code.angularjs.org/1.3.0/docs/api/ng/filter/date

Adding 'UTC' timezone will print the duration.

{{(endTime - startTime) | date: 'H:mm:ss': 'UTC'}}
