Sansa e280v2 clock drift

Hello!

I just bought a Sansa e280v2 8 GB on Ebay recently.

Clock is going late by more than 10 minutes every several hours. I got up late 
today due to this.

I have searched, but didn´t find anything at all about Sansa and wrong-going 
clocks.

Any hints on how to fix it? Is there an extra battery just for the clock?

Otherwise I may try to get a different one from Ebay and sell this one again. 
Or use it for purposes where I do need to rely on a clock.

Thanks,
