Many thanks for your answer. We are currently looking at the NTP servers to
try to identify the problem.

However, do you know why the version 4.1.1 does not have any problem with the
servers with such an offset between them?
Have the algorithm change on the 4.2 version?

Many thanks in advance,

             Two upstream time servers is the worst possible configuration
NTP.  See section 4.3.3. at

             Configure more upstream time servers, at least four, preferably
six or more, and possibly as many as nine.  See all of section 4
(above) and <https://ntp.isc.org/bin/view/Support/StartingNTP4>.

             Once you correct those problems, it will be easier to determine
if there's something else going wrong.
