There was a problem hiding this comment.
I confirm this behavior of DateTimeImmutable::createFromFormat and the resulting bug.

Occasionally timestamps will be fully round (eg. 1234567890.000000) or close to it (eg. 1234567890.000031).
When converting those specific float timestamps to string in SlidingWindow (due to
DateTimeImmutable::createFromFormat), the number is formatted by PHP without any digits. This causes the resulting value of SlidingWindow::getRetryAfter() to be violated with the boolean valuefalse.This patch formats the float to include the decimal digits.
