I think the parsing of 8am UTC is a change for the better, but I’m not sure about June 5 am utc. The previous interpretation seems OK to me, “June 5th in the morning UTC”. In fact, I think it may even be better, because I suspect leaving a unit missing in the middle (i.e. having month and hour, but missing day) may be less likely than the other interpretation (month and day, am meaning sometime in the morning).

I checked and that test string was added as part of a performance improvement, #881, and I imagine it does not come from an actual case found in the internet, which makes it hard to argue either way.

Right it “June 5th in the morning UTC”. is a better interpretation. I am fixing that but I think it's beyond the scope of #894.

So should I open a new issue or maybe directly create a new pull request or fix it in the current PR but that's beyond not directly related to issue #894.

Well, I guess you are right that fixing it is out of the scope of this change and should be a separate issue. It was just bad luck that your change broke it, or rather it was just dumb luck that it was working in the first place.

However, what I would do here is move that scenario into a separate test, with the previous value, and mark the test as an expected failure (xfail), to make it clear that the expected outcome is still the old one, only that Dateparser does not support it yet.

Great after this PR is merged I will create an issue and create a supporting PR

Don’t forget the xfail part, though, I do think that needs to be addressed in this pull request, instead of changing the test expectations.

I am working on it now and by the time you create separate test, with the previous value, and mark the test as an expected failure (xfail) it should be done

by the time you create separate test

I was hoping for you to do that, as it needs to be done as part of this pull request (which is the one that causes the test to fail).

It seems it is broken throughout search_dates and parse function as with other cases like

June 5th pm EST ---> [('June 5th pm EST', datetime.datetime(2021, 6, 24, 17, 0, tzinfo=<StaticTzInfo 'EST'>))]

or

June 5th pm EST ---> ('June 9 pm', datetime.datetime(2021, 6, 24, 21, 0))]

Which is incorrect. I am working on the patch but it will require some time and significant change in other parts of the library and many tests will be broken because they are also incorrect. Or the current interpretation is correct.
