PLEASE NOTE: my time zone is Africa/Johannesburg 0200 so what you see below as the output from timedatectl is correct.
Be very careful of guides telling you to run hwclock —systohc, unless your system time and entire server is running in UTC time, do not set your hardware clock with local time using hwclock —systohc.

Then it dawned upon me to check NTP as I have been experiencing problems with NTP crashing on both upgrades from Ubuntu 14.0 16.04 and even on fresh 16.04 installs.
In order to have an accurate time and time synchronization to work properly, the system has to be configured with the correct timezone.I will simply just provide you with the correct fix and it will take you all of a minute or two to fix.First let me confirm 100% that ntpdate is deprecated in Ubuntu 16.04 which means it is no longer used, yet some genius at Canonical decided not only to include it with fresh new installs of Ubuntu 16.04 despite the fact that it has been replaced with something called timedatectl, but also to keep it when people upgrade instead of warning them during the upgrade process about this very mission critical thing that can totally screw up your server time as happened to me.During the upgrade this NTP bug surfaced and I was not aware of it. When my DNSSEC on bind re-signed a bunch of domain names using DNSSEC it signed them with a date about 16 hours into the future, this resulted in a bunch of signed records in the domains being detected as BOGUS and immediately caused several web sites of mine to go down.
Not immediately knowing the cause of the issue I temporarily disabled DNSSEC on the domains until I could investigate further.
An incorrect system date and time can cause untold problems and it seems a lot of people have encountered a bug with NTP in Ubuntu 16.04 Xenial with the service either not starting up after a reboot or simply crashing all the time.
