- I've experienced the same symptom, and found that the battery was the
- fault. I reasoned that the clock requires an oscillator and other logic
- to be *running*, while the memory section is merely static data retention.
- It seems reasonable that the clock would therefore be more sensitive to
- low battery voltage.
