After installing and getting up ntpd
on a RHEL-like Linux system, see http://www.certdepot.net/rhel7-set-ntp-service for example, you may want to double check iff ntpd
is actually able to perform successfully. There’s a couple of shell commands to employ, most notably ntpstat
and ntpq
as well as timedatectl
more recently with version 7 and up systems. ntpstat
will tell you about the status of the time synchronisation, whereas ntpq
, being executed a few times in a row, shows the servers being selected for synchronisation, the one prefixed by an aterisk as the current master, and the time left since the last synchronisation up the the synchronisation interval in the when
and poll
columns, respectively. timedatectl
furthermore includes timezone and daylight saving information, however, the synchronisation status given here is about to be called into question, see later. So far, iff anything runs fine, you may expect something like this (consider the values changing in the when
column for the second call):

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles –nodigest
