Dunno why people would blame the Celery devs for that bug - if you're setting the clock on production servers to a non-monotonic TZ you are going to have a bad time.
So you basically blame people for living in countries that use daylight saving
time? O_O
Also, I would understand if it were tasks between 2AM and 3AM that run twice
in transition from summer time to winter time (there are two 2:30 that day,
after all), but the bug affected tasks scheduled for the middle of the day.
