I have a timer circuit running lights etc on my vivarium.
Up until yesterday it was working fine.
For some reason now, when I power down and power back on again the clock has not advanced.
If I remove the lithium cell and power down/up the clock displays ??:??:?? (I have also tried a new battery with the same results) so I assume it is not the battery at fault.
I have also swapped the DS1307 chip with the same results.
