Was this machine up and running at the weekend when the leap second was added? You could try the workaround for that and see if it helps
service ntpd ... [by TrevorH]

After I installed ntpd via yum I run the command systemctl enable ntpd.service and rebooted the computer. After I got the shell prompt I run systemctl -a | grep ntp and I got ntpd.service loaded inactive dead. If I start it manually using systemctl start ntpd.service it works fine. Why is that? How can I ensure the ntpd.service will be up and running after reboot?
I have some odd behaviour running ntpd on a rhel 6.5 machine. This machine runs as a virtual machine on a kvm host (also rhel) and this host has the correct time (within a few ms), and an ntpd that keeps it correct.
What I noticed is that after i do an ntpdate -u the time will eventually become good, and usually stay there.
However Red Hat recommends that one runs ntpd also on virtual guests.
MySQL will not autostart uppon booting. It does work when I 'service mysql start' from terminal. MySQL has its own partition on a secondary harddrive and Mysql was installed through apt, not during OS-install. The configuration of mysql is correct, when it's running I can read and modify databases.
I have added 'insserv mysql' to make it start up on boot.
