Ubuntu NTP tips

Tested on Ubuntu 16.04.3 LTS

Normally it is hard to know, in what state NTPD is (there are tens of commands but most of them is cryptic and counterintuitive). However there are nice tips on page https://www.cyberciti.biz/faq/linux-unix-bsd-is-ntp-client-working/. One of them is:

ntpstat

Ntpstat is winner - just install it via:

apt-get install ntpstat

And run it (no arguments needed):

ntpstat
    synchronised to NTP server (147.231.100.5) at stratum 2 
       time correct to within 15 ms
       polling server every 64 s

That's all - clear info and easy to get :-)
