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

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?

Solution

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).
