24 hour dial for alarms?

Good idea :-)

The 12h dial is very good, but as an option it should be possible to have 24h dial too!

BTW it should be possible to do that as a QML tweak too. (but havve not checked that...)

... or even a 24-hour clock option, for all things involving time!
(It should definitely be an option - i.e. not mandatory - though.)

For example, see the Android app "24h Analog Clock" (e.g. on F-Droid)

A widget that provides a resizable 24 hour analog clock, with noon at the top and midnight at the bottom. The widget passively accesses the phone's location and if it gets a fix, will display sunrise, sunset, and twilight times on the clock face.

(I actually wished for this, "but just as a clock", in the comment section for the Sailfish OS app "Swiss Clock" in the Jolla Store.
The Android app works on Jolla, but only when opened (not as a live cover), ,and at least when I last tried, the location function didn't work.)

A 24h analog clock face would need to be visually different to a 12h one. ...but how? Having midnight at the bottom sounds like a good starting point. Could the hands be short lines on the in- and outside of a circle?

Please note that there's no need to create a new clock face for the alarm setting. It's simply a circular dial and would be fine just as it is. Marking the night hours would not be necessary but nice.

Maybe karma is only calculated a few times a day or something - whatever it is please convert this answer to a comment or better open a new post if the problem persists, this really is not an answer to your question don't you think?
