Thanks


I have been using chrony for quite a while and am happy with it. It has the advantage that, for boxes with an intermittant internet connection, it can track the rate of time differential between the local system and the ntp server and adjust the time incrementally while the box is not online, thus keeping the local time more accurate at such times.

Description: Sets your computer's clock from time servers on the Net
It consists of a pair of programs :
`chronyd'. This is a daemon which runs in background on the system. It
obtains measurements (e.g. via the network) of the system's offset
relative to other systems, and adjusts the system time accordingly. For
isolated systems, the user can periodically enter the correct time by hand
(using `chronyc'). In either case, `chronyd' determines the rate at which
the computer gains or loses time, and compensates for this. Chronyd
implements the NTP protocol and can act as either a client or a server.
`chronyc'. This is a command-line driven control and monitoring program.
An administrator can use this to fine-tune various parameters within the
daemon, add or delete servers etc whilst the daemon is running.

What?! Look, somebody's got to have some damn perspective around here.
Boom. Sooner or later ... boom!
