Can anyone help, please, Regards,Hubert
First, try a PMU reset. Instructions: http://support.apple.com/kb/ht1431
If a reset doesn't help, the PRAM or "backup battery" that powers (among other things) the internal clock is likely dead. There are replacement instructions online that can guide you if you're reasonably handy with tools:

Although you can replace the entire card that holds the battery, most people replace only the battery itself. It's a 3032 li-on "coin" battery, 3.5V, that you can buy online or at camera/electronics stores.

Thanks. Indeed, years ago I had the same problem and renewed the battery 3.6V, 1/2AA, leadless lithium. At the same time I reset PMU next to the batterie. I can remember now. But thanks again for your help. Regards,Hubert
You're welcome.
