>The awareness of the where the hand stands still works for local hours though.
It doesn't work for local because there's a fundamental difference of geometry between 12 vs 24 subdivisions of a 360 degree circle.
Look at the screenshot to see that the hour-hand pointing to "8" are different angles (240 degrees vs 300 degrees):
In your clock, it "looks like 10am" instead of 8am because of the accumulated lifetime repetition of reading traditional 12-hour clocks.
