Some years ago, I recall there was a bug in iOS which caused alarms not to update correctly when DST started (or ended), resulting in lots of oversleeping as alarms failed to alarm when expected.[0] Personally, I have a problem with my cheapish Android phone where it will suddenly and for no apparent reason decide it's been moved to UTC, and move the time ahead to UTC. It forgets about this delusion when I restart it. So far this has only happened in the middle of the day (and all it's done is mess up the period it's supposed to be silent during, when I'm at work, thus the downside so far has been a couple annoying dinging noises at my desk). Also, I have a fancy alarm clock which alarms by gradually lighting up the room, instead of by blaring loud noises. I find this a more agreeable way to wake up in the mornings. I also like having a dim, but legible time display on my nightstand to glance at when I wake up in the night, rather than having to press a button on my phone, which is then way too bright to look at in my dark bedroom. Finally, apart from software bugs, single-purpose alarm clocks are quite cheap and reliable. Although it is not in my bedroom anymore, I still have an alarm clock that was my bedside alarm clock when I was in elementary school. It's thirty years old by now, yet it still works perfectly. The alarm function still works (although it's quieter than it once was). The display still is flawless (although it's dimmer than it once was). It's a simple, reliable device. My phone...isn't.
