%N A242063 Analog clock times where the minute hand is on the hour hand (in hhmm format).
%C A242063 The format is loosely defined - leading zeros of both hours and minutes disappear.
%C A242063 Changing the tolerance in the JavaScript program changes the results - try 0.01 for example, and we are allowed 10:54.
%C A242063 It is debatable whether 00:00 should be 12:00, but I have used 00:00. As the clock is analog, 13:05 is not valid - am and pm is usually left to discretion.
