Untested thought experiment - set only positive, non-zero times:
  if (t > 0)
     this->SetTime_t(t)

I'm sure we have a zillion places where we're using a zero time_t
(1-1-1970) to mean "unknown time" in reference files.  I know all of our
reference files do that, for example. (They should, instead, simply omit
the datetime if not known....)
