various PPS types natively. It can use kernel PPS API as well as Precision Time Protocol (PTP) hardware clocks. Most general GPS receivers can be leveraged via GPSD. The latter (and potentially more) can be accessed 859 0.509 -750us 108us You can also track the raw data that gpsd or other ntpd-compliant reference clocks are sending via shared memory by using ntpshmmon. Let us run the command sudo ntpshmmon -o, which specifying an explicit trusted certificate. Bad Clocks and secure time syncing - “A Chicken and Egg” problem There is one problem with systems that have very bad clocks. NTS is based on TLS, and TLS needs a reasonably
