Strange Ticking from Dash

[RWC]

Reposting this in the Boxster General Discussions section, I inadvertently posted it in the wrong section....
HI, I recently purchased my first Porsche, a 2001 Boxster. The car runs great and is a pleasure to drive but I have a strange problem. When it is shut off and the door is closed, I can hear a strange ticking, like a clock, coming from the dash. I noticed that the gauge needles jump a little with each tick. It doesn't seem to be causing any issues and the car starts fine if left for a week so I don't think it is draining the battery too much. I first heard it when I walked into the garage last week.
Has anyone experienced anything like this? If it helps although probably unrelated, the digital clock does not keep time correctly.
Thanks
Ron
