Probably want to have this happen at most once a run. If something were
to break, I don't think we want this to live lock the machine doing
tons of prints. We could have a variable stored on the
osnoise_variables that states this was printed. Check that variable to
see if it wasn't printed during a run (when current_tracer was set),
and print only once if it is.

I created a "bool tainted" variable, that is set true if any problem with time()
related functions happen. I will pr_warn that there is a problem on _start(),
but also print this info at the top of the tracer header, so it is clear also
from the trace output.

Thoughts?
