Hi,

Thanks for the suggestion.

But I could not understand it.

Is there a option of either using ntpd daemon or use of ntpdate in a cron
(Becoz both dont run together due to same port). Is that what you are trying
to explain?

If so, then what is the standard way for linux client?? How do people
implement this on production environment.

Please share your thoughts.

Thanks,

Raj
