In PHP < 8.1, comparing 2 date-times from different timezones would consider the real moment they represent to return the diff, which is completly relevant. But it's no longer true (sounds like introduced by 091c0920b9db057a54dc43ece6e864bce6818d5e).

Test script:
$dtToronto = new DateTime('2012-01-01 00:00:00.000000 America/Toronto');
$dtVancouver = new DateTime('2012-01-01 00:00:00.000000 America/Vancouver');

echo $dtVancouver->diff($dtToronto)->format('%h');

Expected result:

I assume this is related since it was closed with the large patch from derick.
