I've been running weewx for years, and now all of a sudden I am having this
problem over and over again.
Now, this is a new build on this same RPI - I had a SSD crash - but it
seems substantially the same as before, yet here I am.
I realize this has to do with the OS's time not being.... "correct",
whatever that means. So why does this confuse me?
pi@pi3b:~ $ wee_device --info | grep time
Onboard time: 2020-12-27 17:37:04
pi@pi3b:~ $ date
Sun 27 Dec 2020 05:37:09 PM PST
Is this really the cause of my problems?
