What is the expected behavior?

Epoc time '1458874500000' should show 2.55AM and '1458874800000' should show 3.00 AM. Currently '1458874500000' is showing 3.55 AM

Angular date filter should work with DST also.

This happens because of how we are trying to convert to another timezone and Daylight savings.
Daylight savings took effect on 03/25/2016 @ 2:00 AM Israel time. Basically, at that time the "clocks" should be turned one hour ahead (2:00 AM --> 3:00 AM).

The way we are trying to convert from the user's timezone to another one, is by creating a Date object whose values are such that the getXyz() methods (which return local values), will return the appropriate values.
So, for example you are passing a Date that corresponds to @ 02:55 UTC, so we are trying to create a Date object so that getHours() will return 2 (which means 2 in your local timezone). But there is no such object, because there is no @ 02:00 local time in Israel (since clocks "jumped" form 01:59:59.999 to 03:00:00.000).

I'm not sure whether this is fixable (in a sane and reliable way), but will look into it.

Thanks gkalpak for looking into this. Can you please let us know the approximate timeline of when the fix would be available?

[gkalpak]

@JanyJose, it's not a high priority atm, so there is no specific timeline.

gkalpak,

I am also facing the same issue, can you please let me know in which version the fix is/will be available?
If not so please provide at least workaround for the issue.

Thanks,
Jitendra

@raijitendra, I didn't have the chance to work on this yet. (Like I said, it is not a high priority.)
It is still on my TODO list, so I will update the issue if/when I get to it.

[raijitendra]

@gkalpak It could be helpful if some workaround is provided.
