It seems that in Raspian Stretch, timesyncd is enabled by default. And, it too attempts to read the date/time from a file when booting. I had removed fake-hwclock, but still had some problems with the date/time on reboot. Looking into syslog I saw the following Mar 11 15:39:47 xxxx systemd-timesyncd[342]: System clock time unset or jumped backwards, restoring from recorded timestamp: Mon 2019-03-11 15:39:46 EDT I ended up disabling timesyncd via sudo systemctl disable systemd-timesyncd and installing ntpd via sudo apt-get install ntp
On reboot I now see that weewx is "Waiting for sane time.". Hope this helps others who might not have installed an RTC.
