I know this is old, but I’m having the same issue with the unified firmware. When OS boots up it gets correct time from (my local) NTP server and displays correct time in the web UI. Sometime after (hours or minutes), the time switches to this: Feb 06, 2106 02:58:49. This is repeatable.
This is all I have in the serial debug output:
(That’s the output from boot, there is no further output when the time gets screwed up).
I have not configured a Weather Underground key (assuming that this is OK), and the forecast is displayed correctly and for correct dates.
Attached is the diagnostic screen. Note that OS has been up for only about an hour, but “Last Request” and “Last Reboot” are both completely wrong (screenshot is from April 9, 2020)
Happy to provide further details or let me know what I should try on my end.
(I’m running the latest master firmware with some tweaks for my relays, nothing to do with NTP. I can load clean master branch as well for a test)
