Time definitions
The error of a clock is the difference between the actual time of the clock, and the time the clock is
intended to have. The rate accuracy of a clock is normally called the clock accuracy and means how
much the error increases, that is how much the clock gains or loses time. A disciplined (trained)
clock knows its own faults and tries to compensate for them.
