I noticed today that the iPhone app was relaying a random date/time in the year 2036 from my OpenSprinkler 2.x unit. NTP sync is “ON”. I forced a reboot through the iPhone app twice to no avail. I then turned NTP Sync “OFF”, rebooted, turned NTP Sync back “ON”, rebooted, and the correct time showed up. I don’t know how long the wrong time has been showing – it might have been over a month.
