I discovered that my OpenSprinkler had the wrong time/date this morning and rebooting did not fix it. I finally looked up IP addresses for public NTP servers and changed mine to a new one. Immediately after saving the change the time/date were correct. I don’t recall where I got the old IP address for my time server but I’ve been using it since I first installed years ago. The time has been wrong for a long time but today was the first day I expected it to run this year.
