Description: The threshold in milli-seconds whether to decide to set the received SNTP time directly to the local clock or not. If the hmNetSNTPTimeAdjustThreshold value is 0, the received SNTP time will be set directly to the local clock every time a SNTP message is received. If the difference between the local clock time and the received SNTP time is fewer than the hmNetSNTPTimeAdjustThreshold value, the local clock will not be set. If the difference between the local clock time and the received SNTP time is equal or larger than the hmNetSNTPTimeAdjustThreshold value, the local clock will be set.
