I read this a while ago and was looking forward to the mess that would happen with these default Alpine configurations (after setting non-UTC localtime)

    0 2 * * * run-parts /etc/periodic/daily
    0 3 * * 6 run-parts /etc/periodic/weekly
It appears that busybox cron is smart enough to handle it and only ran the jobs once.

Google's AI and ChatGPT answer disagrees.

https://www.google.com/search?q=busybox+cron+dst

"BusyBox’s crond is a lightweight implementation designed for embedded systems, so it doesn’t have all the timezone/DST logic of full vixie-cron or cronie. It just reads /etc/TZ or the system timezone at startup and then wakes up every minute to check if something should run."

Please don't do this. AI is not a source and is frequently wrong (as it is in this case).

You're right. It was honestly just a low effort semi-sarcastic reply that I wasn't really expecting anyone to take seriously. I should have just gone and read the source code as PhilipRoman did below.
