Anybody know about tracker data and insurance claims?

A couple of months ago a removal truck hit the front end of my car while it was parked on a side road near work. I didn't see it, there were no details but luckily a couple of people saw what happened and agreed to be witnesses for police and insurance purposes.

Today my insurance company called and says the firm's insurer has provided tracker details to prove that the vehicle wast in the area at the time of the accident. For some reason, they seem to think it happened at a certain time, when it was actually a pretty big window in the afternoon.

Do trackers record the entire journeys or the start and end points? I'm hoping they're trying it on and the complete days's records will show it was on the road the accident took place on (removal firm was also doing a job on that road).

I guess I'm getting a bit twitchy because my insurer says that tracker info will trump a witness.
