My solution was to install ntp, plus add a wait routine in bin/user/extensions that waits for ntpq -pn to report sync'd time. I use that code on the rest of my Rpi's as well. Can send if interested. FWIW, the RPi that runs my weather station does have a RTC stacked on the serial port (pre-dates said code block).
