*2 The GP's internal clock has a slight error. At normal operating temperatures
and with the GP's power turned OFF, i.e. in "backup mode", 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 adjustments when required.
