I suspect they are both just telling you about a timestamp was embedded in the client request packet?
If you look at the date outputs you pasted:
[ifts@localhost ~]$ date
Thu Nov 12 13:46:16 CST 2020
ifts@stone:~$ date
Thu Nov 12 14:10:03 CST 2020
Those are indeed quite different, and fwknopd is doing the right thing.
