I'd suggest using the internal EEPROM.

Or a separate RTC with it's own backup battery.
ex. philips PCF8593/PCF8583 i2c RTC.

Or an external non-volatile memory, flash, eeprom .......

Yes, and in addition to a FAQ, I've missed some
AVR-specific GCC-docs ....

Try www.avrfreaks.net ....

Let's hope that the ones who have the knowledge don't
get tired of helping us (atleast me :-) for whom everything
ain't clear as water ....
