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.
