IMO, adding a RTC to an internet connected device seems redundant and doubly redundant when already connected to a device with a battery backed RTC like the Davis Vantage console.
browsing the vantage drive source there is already code for retrieving the console time. compare the retrieved time from the console to rpi system time, if more than max_drift make a call to set system time. this would remedy the OP's problem. when the rpi gets a time update from an NTP source weewx will compare and update the time on the console. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
