OpenSprinkler Forums Hardware Questions Router Causes clock to jump back Re: Re: Router Causes clock to jump back



After a week of being off, I connected to internet LAN and time showed all zeros

This is typically due to a soldering problem on the battery holder, causing the battery to be disconnected from the RTC. Without battery the RTC will reset to 00:00 on start up. Check the solder joints of the battery holder and see if a pin may be lifted. Re-soldering it should solve the problem.
