When it is an odd request in your opinion, it does not mean it is
not valid. It may explain why there is no standard code in ntpd
to handle this situation, but it is no excuse to give wrong answers
or boilerplate answers.
It happens so often on this group. There are two questions that
very frequently pop up:
- I want to test and validate how ntpd handles an unusual situation
(like a fault or a leap-second)
- I want to keep an island of sytems synchronized to the same time
(but I don't care how that time relates to UTC)
All the time we see those responses that declare the question as
odd, or try to modify the requirements of the poster, or add a new
piece of hardware (like a GPS receiver).
And usually the responses are from the same small group of posters.
It is really lame. When you cannot answer the question, you can
always keep quiet. There is no need to always jump on the soapbox.
