I have gone through several tutorials regarding NTP and synchronizing the system clock, but I am still not able to get my system's time right. I followed the following steps on a machine running Ubuntu 16.04 LTS:Installed ntp and ntpdateEdited the /etc/ntp.conf file to contain the following:driftfile /var/lib/ntp/ntp.driftserver 0.pool.ntp.org iburstserver 1.pool.ntp.org iburstserver 2.pool.ntp.org iburstserver 3.pool.ntp.org iburst`Started the ntp service with sudo /etc/init.d/ntp startTo check if everything was working, I ran ntpstat and got this output:unsynchronised   polling server every 8 sChecking with ntpdc -c peers returned: localhost: timed out, nothing received***Request timed outntpq -p gives:    `remote          refid           st t when poll reach   delay    offset jitter`   `==============================================================================`   `propjet.latt.ne .INIT.          16 u    -  512    0    0.000    0.000   0.000`   `duffman.whacker .INIT.          16 u    -  512    0    0.000    0.000   0.000`   `ec2-52-6-191-28 .INIT.          16 u    -  512    0    0.000    0.000   0.000`   `104.131.53.252  .INIT.          16 u    -  512    0    0.000    0.000   0.000`Even after all of this, my clock is still off by almost 10 minutes, and I'm not sure what the issue is.I am running a local machine, but it is behind a corporate proxy. However, I've included the proxy information as environment variables. Are there any corrections that I can make to fix this?
