I just checked and things seem to be working once again. However, data is missing around 03:00 yesterday until around 14:00 today. I was planning on installing the RTC but saw no need since I assumed that the system would get the correct time from a time server. This, evidently, was an incorrect assumption. Do you have any idea on why this did not happen? Why did it take so long to begin displaying "correctly" again. I would have thought that it would start up right after the reboot. Does Weewx itself query a time server or do I have to explicitly do this?
Speaking of "explicitly", I wanted to explicitly thank you and other group members for their help for those of us that need it. Thank you.
