How can I tell if my Debian system is keeping the system time accurate by getting NTP updates?  Basically I want to turn this on if it is currently off, but I don't know if it is on or off.
How can I tell if my system is keeping the system time up to date?
debian;ntpd
Running ps ax | grep ntpd and checking that the output contains something like 6497   ?     Ss    0:04    /usr/sbin/ntpd ...will confirm that ntpd is running. If it's not running then you can start it with /etc/init.d/ntp startIf you get an error message No such file or directory then you will have to install the ntp packagesudo apt-get install ntpOnce you have ntpd running you can talk to it with the ntpq command.ntpq -p      remote           refid      st t when poll reach   delay   offset  jitter==============================================================================*time.nist.gov   .ACTS.           1 u  753 1024  377  139.432   -0.562   2.199+sip.dicode.nl   193.190.230.66   2 u  733 1024  163   33.197    0.297   0.132+194.109.64.200  192.87.106.2     2 u  779 1024  377   35.214   -0.323   0.027 LOCAL(0)        .LOCL.          10 l    3   64  377    0.000    0.000   0.001Which shows (offset) that my system is <1 second out of sync - I can live with that.
