I would not either - I would only go so far as to say that we've inspected
it, corrected some potential problems & found nothing serious.  (But like
all programs, it may still have problems that we have not diagnosed).  I
noted this in the README.

I understood that - thanks.

I did check PDM's mktime.c (by writing a simple test, stepping through several
years back/ahead 1 hour per step) just to verify the algorithm, since the
handling of leap year was not apparent (yes, I'm aware that there are compact
algorithms for it, but I've not memorized them ;-).  It's ok, so I made no
further mention.
