Its about time was created by eran579. Check the game here.Three games - versions on checking how good can a user determine how much time has elapsed between two events.
1. Stop on time : The user first determines a number of seconds. Then he is expected to press a keyboard key twice, where the time between his two
presses should be as close as he can to the number of seconds he determined.
2. Estimate time : The user first detemrines minimum and maximum number of seconds. The he sees on the screen a START message, followed - after a
while - by an END message. The user should try and estimate how much time exactly passed between the START and END messages (which is, of course,
within the limits set initially by him).
3. Stop any time and then estimate : The user presses a keyboard key, and after a while - whenever he wishes - another press. Finally the user
should try and estimate how much time exactly passed between his two presses.
