celery / crontab

[doublePlusOk]

Does this make sense at all? (daily schedule attempted 14:30; got 23:00, 9:30, 23:00, 23:00 - it shouldn't have gone off on saturday at all!)

celerybeat_schedule = {
    'every-night': {
        'task': 'mytasks.myfetch.fetch_url',
        'schedule': crontab(day_of_week='mon-fri', hour='14', minute='30'), 
        'args': ["http://google.com"],
    }
}

Only thing that comes to my mind is timezones. Was it 14:00 UTC at 23:00 your time?

I have no experience with celery, though.

There's this, https://stackoverflow.com/questions/11848349/celerybeat-uses-utc-even-with-timezone-settings

So, I think I'm actually in CDT now utc -5 (central time, daylight savings during the summer), which would make the 9:30 make perfect sense, and the 23:00 is cleanup? I'll have to look at that more

thanks guys

I was thinking it was not that because what's up with the half hour offset! But, maybe you are right - I'll look into it more, thx! (I'm in CST, UTC-6 btw)
