    Well, on a more serious note, it is odd that some microwaves let you type in 90 and time down from “90” instead of “1:30”. I should type in something like 190 and see what it does. My bet is it only does the weird seconds format when it’s 99 seconds or less. Because obviously 100 would be a minute, not 100 seconds.

      I tried 190. Its counts down 90 seconds to 1:00 before rolling over to 0:59.
      190 is 2 minutes and 30 seconds.

      I’ve also tried 0 and it just beeps.

        I love that someone made that feature.

        “Look, people are morons, just let them enter up to 99 seconds”

          It’s just a display that’s 00:00 to 99:99 it’s the simplest possible logic for the use case.

          That’s why 00:90 is longer then 01:00. And +1:00 is less than +00:60 sometimes. You have to roll over 00:99 with +00:01 to hit 01:00.

          Iv rarely seen some microwaves with a +1 second button and they act this way.

          Like microwaves best as I can tell have worked like this since the 70s the expections are absurdly rare.

      I used to have an old digital 24h clock and one time I was watching close to midnight. It went from 23:58 to 23:59, then a minute later 24:00 blinked for a second before it went to 0:00.

        ISO-8601 has some cases where 24:00 is allowed in place of 0:00, or at least it used to. Maybe new editions removed it.

          Sure, but not for one second before reconsidering. That was some weird jank in the way the clock was put together.

      Honestly it’s a nice feature.

      I have a thing that takes 45 seconds to warm. I take two of them, type in 90 and it just works!

      Of course that breaks down if I take four of them and type in 180, but meh. Worst case is that it’ll be a little cold.

        Well hold your horses, why does heating up two take exactly twice as long? Your microwave heats everything inside. I can understand it being longer, but exactly twice as long? Hmmm… I think we need more data.

          why does heating up two take exactly twice as long?

          A microwave works by exciting the water molecules in an object. They start to vibrate from the microwave energy hitting it, and vibrating molecules is what heat is. The microwave energy mostly bounces around inside the metal microwave until it hits something that has water (which is why you should never turn it on empty), so it doesn’t really get wasted.

          So, if you put twice as much stuff inside, it will take twice as much energy to heat it to the same temperature, so at the same setting it will take twice as much time.

          If you want to get nitpicky, it will require very slightly over twice as long, because by needing more time to warm up, it will give off more energy to the air around it, so you need to compensate. But the question of “how much will my food cool down in 90 seconds compared to 45 seconds” should be answered by “shut up dude” and not with a number.

      Microwaves basically always assume leading zeros so microwaves are ALWAYS in 00:00 format no matter what’s displayed.

      So 90 is 00:90, and the max it can do is 99:99 the moment you realize this everything makes perfect sense why they act that way.
