Silent Hill 3 Forum  /  Timer question.

The timer is set to update every 1000ms as to minimise resource usage. It's not synchronised with the game so the 1000ms recheck occurs even if the game is paused etc.

It also rounds up decimal places, when the in game time rounds down, so there is a chance of 1 second inaccuracy, it's worth checking your time in the results screen just in case.
