2.2.3 Clock
The GP’s internal clock has a slight error. At normal operating temperatures and
conditions, with the GP operating from its lithium battery, the degree of error is 65
seconds per month. Variations in operating conditions and battery life can cause this
error to vary from -380 to +90 seconds per month. For systems where this degree of
error will be a problem, the user should be sure to monitor this error and make ad-
justments when required.
