Description

Every few commits, there's now a random PHP 7.1 test failure on Travis, mostly off-by-one errors unrelated to the preceding commit. Started about 1 month ago, after August 20th.

Seems like either PHP 7.1 tests are for some reason more prone to random errors than other versions, or it's just more prominent now that random date/time failures from #45821 are fixed.

Creating a ticket just for reference, any ideas as to why this happens appreciated.
