I think that the problem is that DST is a really, really bad idea. So you have a process that starts at 1:30am on November 6, 2022. If that's in Ontario, is that the first 1:30am or the second one? (At 2:00am, clocks go back to 1:00am, so we do that hour again. If the process is supposed to start at 2:30am on March 12, 2023, that's too bad, because at 2:00am the time jumps to 3:00am, so no times from 2:00am to 2:59:59am are valid. And now some regions are abandoning DST and others aren't. I'm not sure if it's still the case, but in Indiana one part of the state was on Central Time and another part on Eastern Time, and both observed DST. There was a third part that was on Central Time but did not observe DST, so part of the year it would match Central Time and the rest of the year it matched Eastern Time (IIRC).
