settings.js: wrap time

I was a bit annoyed that when setting the time the hours did not wrap.
So when going up it would stuck at 23 instead of wrapping to 0 and when going down it would be stuck at 0.

I tried to change this by modifying the Hour section of showSetTimeMenu in settings.js to this:

'Hour': {
      value: d.getHours(),
      min: -1,
      max: 24,
      step: 1,
      onchange: v => {
        d = new Date();
        d.setHours((v+24)%24);
        setTime(d.getTime() / 1000);
      }
    },

I thought that would to the trick but to no avail.
I did overwrite settings.js on the bangle; that did not work, then I rebooted but still no luck.
I've read back settings.js to verify that it is actually the modified version and it is.
What am I doing wrong ???
