We know that max seconds of transmiting message updating time among different clients by the ntp are 2^32 seconds, but time difference are only 2 years between server and clinet actually. So I do not know how is it ? Can someone give me some suggestions, thank you in advance！

more information would be helpful. What version of ntpd are you running? ntpd has its build date compiled in, so it knows "now" time cannot be earlier than this date.

Behavior like you describe has only been observed when a human decides to try crazy dates.
