Render negative times
This is particularly important for timers like Google Home that don'stay while ringing until explicitly dismissed; this lets me see how long the timer was ringing for.
I did not verify that all of the rounding behaves correctly.
Interesting! I hadn't even noticed, but you snuck in the ability to render negative times with the state: { fixed }. Thanks for fixing up this hidden feature.
I took a look at the rounding and it is inconsistent. h, m, and s all round down to smaller magnitude times. Meanwhile, hms and hm round up. I think rounding down here is the correct behavior, so that if you're rounding a timer that's run 1 second over to the nearest hour, you get a 0 instead of the timer immediately jumping to -1 once it's finished.
In terms of implementation, you should be able to leave the hmsTime and hmTime alone, and instead patch joinWithColons to handle the negatives.
I didn't actually realize that negative times weren't previously possible; I just noticed the incorrect behavior in my dashboard.
Fixed.
Ah; I see what you mean now.
How's this?
I noticed some more issues and added more test coverage.
Looks perfect! Thanks so much for bearing with all the reviews and adding those additional tests.
Things are busy this week but I'll try to get a new release with these changes included next weekend.
