If you know the path, you also know it starts at 0 and ends at 1. That is a direction. In order to 'read' where you are you need to define the nearest point on curve, then read the time. You need to save this number and chech if greater, if not, you are going back.
Polygonal made a nice demo, and his framework does all the complex stuffs for you. Hope it helps a bit.
