2.2.3 Clock (RTC) Accuracy

Clock(RTC) accuracy
The PL unit's built-in clock (RTC) has a slight error. At the PL's specified ambient
temperature and with the power turned OFF the error is +180 seconds per month.
However, ambient temperature fluctuations and the age of the unit may increase
this error to +300 seconds per month. If the PL unit's RTC clock accuracy is vital
to system performance, regular adjustment of this clock is required.
