Double click the green flag. Use B to change the backdrop color. Use space to change the clock type. Watch the the second hand goes around the clock too many times a day. Watch the minute go around 1440 times a day. Watch the hour hand go around the clock 24 times a day. Watch the date change too. I turned it into a game. See if you can find out how.
The outer ring of numbers is the hours and the inner ring is the seconds or minutes. (only in the first clock)
