The problem with the 24-hour clock
The problem with the 24-hour clock is the teens. Not '1300', and not -- speaking from experience -- 1400 or 1500. But '1600' makes me think, even after many years familiarity with the system, of '6 O'Clock', not 4pm and '1800' brings '8 O'Clock' to mind rather than 6. Oddly, as I think about it, I don't really have this problem with 1700 or 1900; and obviously the 20s don't correspond to a 'pm' timeslot. I wonder why the ambiguity is limited, for my stubborn brain, to those two times?
