But on a nearly identical Intel based system, (as well as on a Raspberry Pi 20.04 or an Ubuntu 18.04 system), there are no problems whatsoever :

I have been searching the 'net, and tried a number of alternatives (e.g. chrony and systemd-timesyncd), but none of them are good alternatives. Please note that "pjjrpiz.pj.org" is a self built in-house GPS based NTP server running on yet another Raspberry Pi.
Any support you may be able to offer will be appreciated ! if there are any other tests or actions you would like me to take to try fixing this annoying problem, probably only on this AMD 5700G CPU based system (in an ASUS Desktop X300M system), please just ask.
Thanks for all your efforts.
