The Network Time Protocol (NTP) daemon provided by the
ntp-simple
package is by far the easiest way to manage the
accuracy of your clock, particularly if you are connected to the
internet (even if only intermittently).
The ntp-simple
daemon (ntpd) effectively sets
the clock by speeding it up or slowing it down depending on its natural
drift so that it gets in sync and stays there. This avoids a ``sudden
shock'' to the system with a dramatic change to the time, although
mostly the system can handle it.
The primary configuration required is to identify an NTP server. Look
at the lists at https://www.eecis.udel.edu/~ntp/, for example.
After running ntpd for a little while your clock will be
set to an accurate time and will maintain an accurate time. However,
if the amount of difference is too great then ntpd will
not modify the clock. After setting up ntp-simple
you can
install ntpdate
and on install (and reboot) the clock will
be updated to the correct time according to the server you have chosen
for ntp-simple.
With ntp-simple
installed on one of your hosts,
Velox (101.31) for example, on the local network you can now use
Velox (101.31) as a ntp server simply by installing ntp on each
machine and pointing them to Velox (101.31) as the server.
