Time smoothing determines an offset that needs to be applied to the cooked time to make it smooth for external observers. Observed offset and frequency change slowly and there are no discontinuities. This can be used on an NTP server to make it easier for the clients to track the time and keep their clocks close together even when large offset or frequency corrections are applied to the server's clock (e.g. after being offline for longer time). Accumulated offset and frequency are smoothed out in three stages. In the first stage, the frequency is changed at a constant rate (wander) up to a maximum, in the second stage the frequency stays at the maximum for as long as needed and in the third stage the frequency is brought back to zero. Time smoothing is configured by the smoothtime directive. It takes two arguments, maximum frequency offset and maximum wander. It's disabled by default.
