I thought someone was gonna ask how I got the score XD
Anyway, the timer isn't wholly accurate. It could either be a hack or that was the amount of time that he/she played the game, not necessecarily the amount of time spent to get the score.
lvra is correct. The timer only reflects the amount of time spent completing the last game the user played. In this case, FlyingSnow started and ended a game within two seconds.
