WebWhen frequency tolerance is say 100ppm, then your 1MHz clock will have a frequency in the 1 000 000 Hz +/- 100 Hz. This says nothing about jitter. Frequency is only the … WebClock synchronization. Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.

WebJust to add some data about why NTPD is not a good solution. NTPD is a daemon that tries to compensate for the local clock drift; if the "internal clock" drifts away by X number of seconds in a day, then instead of jumping ahead/back like a forced command as in "ntpdate " NTPD tries to add/remove some cycles to the clock so that in time, normally within 15 … WebFeb 8, 2024 · Conclusion.
