Angular DatePipe - Convert seconds to time with zero timezone (12 instead of 00)

Question

I want to convert number (which represents seconds) using DatePipe to get result like this :

00:00:05

I've tried doing so with DatePipe this way:

<label>No timezone (default) {{ 5 * 1000 | date:'h:mm:ss'}}</label>

But it produces result with timezone +4 included (which is not what I want):

4:00:05

So in order to avoid this I'm trying to set timezone offset to 0:

<label>{{ 5 * 1000 | date:'h:mm:ss z':'+0000'}}</label>
<label>{{ 5 * 1000 | date:'h:mm:ss z':'UTC'}}</label>
<label>{{ 5 * 1000 | date:'h:mm:ss z':'GMT'}}</label>
<label>{{ 5 * 1000 | date:'h:mm:ss z':'GMT+0'}}</label>
<label>{{ 5 * 1000 | date:'h:mm:ss z':'UTC+0'}}</label>

But this time the time is shifted with 12 hours instead of 0:

12:00:05 GMT+0

So is there a way to convert seconds to time with DatePipe without shifted timezone?
Or is there any other pipe by angular which can be used for this purpose?

Answer 1

So this quite tricky problem has a quite simple solution.
We just have to use 'H' instead of 'h' (range of which is 0-23).
Example:

<label>{{ 5 * 1000 | date:'H:mm:ss':'UTC'}}</label>

The reason of getting '12' was the usage of 'h' in time format which limits values from 1 to 12 and converts 00:00 to 12:00 (AM).
