I was just trying anything to see if there was a way to solve my original
issue. Me mentioning the selectdata call was also just to inform that I can't
get the call to work in general. Chronyc didn't seem to recognize it. I was
just trying out all the commands in the chronyc documentation. Apologies that I
wasn't more clear.

That could work. Currently my setup is mentioned above. It would sure save a
lot of calls. In the meantime however, do you have any advice or suggestion on
how to workaround my issue?
Thank you,
Ben Chang

No, refclocks cannot be added by chronyc. When chronyd is already running, it's
not expected to have the permissions needed to open reference clocks.
There could be a new command added to change the offset of existing sources.

I'm not sure what problem this is trying to solve.
