ArcaOS uses Clock Synchronization to adjust for Daylight Savings Time (DST) adjustments. The time just changed in my part of the world, and when I sat down at the computer, it was still on DST. So I synchronized manually again this year.
But while I was doing it, I noticed something. ArcaOS is set up to synchronize every 720 minutes. But I get up early, and it's only been 240 minutes since the time changed. I changed the 720 to 180, and I'm going to see if it works next time the time changes, March 8, 2026.
