Check if NTP update is successfull by comparing the new time with time at last NTP Update + time gone since then

Hello, is it possible to add a feature where the new NTP time from the NTP server is checked to be valid by comparing the new time with the old time + time between the updates? Since normal uC are not very precise maybe by adding a tolerance of x% for the time between the updates?

I sometimes get a single wrong update.

Another possibility would be to compare the result of x UDP requests with each other to be certain, the update is succesfull.

Greetings Michael
