The SNMP MIB RFCs are notorious for including magic blue sky values and
measurements that nobody knows how to measure and that are not well defined.
For things that don't make enough sense, it's ok to not implement that
particular snmp variable.
As for the "Check if ntpd configuration changed", that appears to me to be

number" is better retrieved from one of the system MIBs. It's okay to not
