General concepts
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. Clock accuracy indicates the increase in error, that is, the time
gained or lost by the clock. A disciplined clock knows its own faults and tries to
compensate for them.
