Add test for bug #52480

[michaelmoussa]

The bug seems to manifest depending on the timezone, so this test iterates through all available timezones to verify each calculated interval is correct.

The expect section does not look correct.

[michaelmoussa]

@krakjoe if the date math works correctly, then the expected output is a long string of 1s.

A series of strings with the timezone and result so it's more explicit might be better, i.e. UTC:1\n and so on, but the objective is to test that the math works out, not that there's any specific number or ordering of timezones.

Do you have a better suggestion/preference? I'm happy to modify it if so.

[krakjoe]

Sorry, I misread the diff (didn't notice +) ...

The test fails, but I guess that's expected ... if it's expected can you add an xfail section please ?

[nikic]

What we usually do for tests like this is not output anything in the success case and have a

?>
===DONE===
--EXPECT--
===DONE===

as the expectation.

@weltling Can you please check the AppVeyor build? The test is failing and it says NMAKE : fatal error U1077: 'C:\obj\Release\php.exe' : return code '0x1', but the whole build passes.

[michaelmoussa]

@krakjoe, I added XFAIL and ===DONE=== expectation for success case per @nikic's suggestion.

[weltling]

@nikic yeah, that's fishy, looking after it now. Seems something changed at least with master, not yet clear to me where.

Thanks.
