The GLC unit’s internal clock has a slight error. At normal
operating temperatures and conditions, with the GLC operat-
ing 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 prob-
lem, the user should be sure to monitor this error and make
adjustments when required.
