IEEE8021ASClockAccuracyValue
Characterizes local clock for the purpose of the best master clock algorithm. The value shall be selected as follows: a) clockAccuracy is set to the value that reflects the combination of the LocalClock and ClockSource entities if specified or known; b) if the value that reflects the LocalClock and ClockSource entities is not specified or unknown, clockAccuracy is set to 254.
