Brad,
Thanks for your reply.
Actually my requirement is to run a clock which can be controlled by NTP
daemon process.
That's the system clock.
I want NTP to manage the clock functionality to do on my
clock not on the system clock.
What is your clock if it isn't the system clock?
Actually a virtual clock shall be maintained by
the NTP daemon process with system clock functionality.
Well NTP already does that. That's how it figures out by how much to
adjust the system clock.
Because the system
clock shall be controlled by some other program in the network,
No, your clock MUST be controlled by a process running on the same
platform. If that process get information or instructions from somewhere
else that is irrelevant since NTP already does that.
this shall
distribute the TOD to the entire network including my processor. This TOD
clock sometime may be set by the user manually.
Why?
This TOD process shall get the
time info from the NTP process, the clock we mention here.
If you get this from NTP you cannot set the clock manually since NTP
will correct the clock.
Is there any
provision in the existing NTP to implement this functionality or we need to
add some source to have this functionality done.
What functionality are you asking about? Do you understand your own
question?
We want this NTP clock should be an isolated one. We do not want NTP to set
system clock.
NTP can run in an isolated network but it makes no sense to not set the
clock. You can prevent it from setting the system clock but then you are
running NTP for no clear purpose.
I've attached the architecture diagram to make it further clear on the
requirement.
You cannot attach anything to the mailing list. Post a URL which points
to the diagram.
My intention is not to modify the source and finding out the
implementation options from the NTP experts to implement this.
Thanks
Sivakumar
What's the real purpose behind this. What are you really trying to do?
