I use the OS default, which on CentOS 7 is chrony, unless there is
some reason to do otherwise. One example of that is Cloudera Hadoop,
if my limited familiarity with it and memory of it is correct. The
monitoring software looks for NTPD, so that's what we use there.
If the time gets set properly and it's low maintenance, I don't care
what's used, apart from a slight preference for using what most people
would expect I'd be using (install with the fewest possible exceptions
that might need to be documented in an ideal world).
