There are a couple of small issues with the sync'ing of the live time display:

1. when joining a course the timer display starts immediatley from 00:00:01 and displays 00:00:02 before the player has had a chance to move;

2. when finishing the course the timer always displays 1 second more than the actual finish time - see pic

One way to fix both issues is by delaying the timer start by 20 ticks (1 sec).
