The test forced a rollover by back-dating the file modification time, but the rollover time is now based also on the creation time, which cannot be changed. Instead, set the rollover time one second after the file creation time and wait until the clock reaches it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The test
test_rollover_at_midnight(andtest_rollover_at_weekday) became unstable on Windows after gh-84649, which madeTimedRotatingFileHandlerbase the rollover time on the minimum of the file creation and modification times. The test forced a rollover by back-dating the modification time, but the creation time cannot be changed, so the file no longer reliably looked old enough and the rollover did not happen.Instead of moving the file's timestamps into the past, set the rollover time (
atTime) one second after the file creation time and wait until the clock reaches it. This keeps the one-second offset that exercises theatTimerounding incomputeRollover()while no longer depending on the ability to change the file times.
