WebFirst you'll need to get the right time set on the Pi, the easiest way is to connect it up to Ethernet or Wifi - it will automatically set the time from the network. Once the time is correct (check with the date command), run sudo hwclock -w to write the system time to the RTC You can then verify it with sudo hwclock -r WebFeb 21, 2024 · In addition to the "unreliable network" operation, chrony can make a larger correction to the system clock frequency. If the difference between nominal clock frequency and observed clock frequency is more than ±500 parts per million, ntpd will not correct it. Basically, chrony works better in a virtual machine than ntpd. – Chad Farmer

WebSep 30, 2024 · That's disappointing to hear; I recently added a SparkFun GPS module to one of my Pis and had been planning to use Chrony to sync time from it.
