clock is late

[The Machine Cat]

I have had my new 08 bike for a little more than a week and the clock is already 30 minutes late...
I find it kind of weird... Any idea what would cause such a thing ?
Except for me riding too fast and entering into some sort of time dilation...

That's funny as mine did exactly the same after a week????? Reset and keep an eye on it.
