Many people are.  We jus tnot sure which ones.  :-)

Yes.

Wrong question, it does not matter even if it did.  step_systime()
takes the amount to step as a double.  Any pivot info is long
gone.  step_systime() just adds step to the current sys clock time
and then sets that time.  But in a very long and obfuscated way.

Unrelated to this issue. That happens in ntpd/ntp_loopfilter.c
So a question for another thread.  Let's not continue to get lost
bouncing around.
