I'm not seeing how that's much of a WTF. When specifying a time duration or interval, you aren't bound to < 60 seconds like you are when interpreting the time on a clock. I think everyone understands this. Lots of recipes and heating instructions on food packaging use cooking durations in seconds or minutes >= 60. "90 seconds" is easier to read and understand than "1 minute 30 seconds." And besides, what else is '9-0-Start' supposed to mean to a microwave? The alternative is to just show an error, which would be a far worse UX than just assuming (with high accuracy) that the user meant 90 seconds.
