I’m having a similar problem.
My version is 1.8.2 and the date shows 2036 for the year.
The time has been working ok for the last 6-8 months and just recently stopped working.
One factor is that I just installed NetTalk ( a VOIP telephone). I suppose this could have changed the setup.
I don’t care about remote access for OpenSprinkler I just want to get the time running again.
What are the steps to fixing this? I can’t find any Network features that let me manage IP addresses for OpenSprinkler.
What am I missing?
