Works like strftime() but allows for multiple occurences of the formatting tokens, just like sprintf(). Also, add capability for 'O' (uppercase letter “oh”) which creates an ordinal day suffix, 'K' for the shorted 24 hour format possible ('8' instead of '08:00', '12' for '12:00', '12:15' for '12:15'), 'L' for the shortest 12 hour format possible…
