Hunter 44860 Thermostat - continually res...

I have a Hunter 44860 thermostat. I've had it since December 2008. Usually it works fine. But the end of Daylight Savings has created an issue. Sunday 11/1, we woke to a cold house. The thermostat thought it was 1:17am, when it was 9am. I reset the time and everything was fine, until this Sunday. I checked the thermostat in the evening (the weather had been warm, so I didn't notice the heat not coming on). Again, the clock claimed it was 1:12am. The minutes were right, but the hour was wrong. Is this an issue with the Daylight savings time reset? Is the thermostat in a loop? I've turned off the Daylight feature in hopes that will work. Any other ideas? Or do you know if there is an issue?
