It can't be that, since I don't know how to enter Apple Diagnostic mode! I do a lot of recording, and every once in a while the file that is created has an unexpected name. I eventually realized that the system date was changed to 2008, and the file name is created from the date and time.
I have been trying to figure out if it is some series of actions on my part, but it seems to happen at random times. Some times it changes within a day of my resetting the date and some times it goes for several weeks.
I know that is not helpful to someone who is trying to duplicate the problem, and I will keep trying to "make" it happen through some confirmable series of actions. In the mean time, I was wondering if this problem is known, or if anyone else has noticed it.
