The whole point was to compare to a preceding time to make sure the timestamp
didn't go backwards - exactly as it can do:-/.  Comparing to a reference file
doesn't prove that unless you've checked the reference file...

Making use of more of a reference file's timestamps could be useful for other
checks, though.

I don't know either.  Ask the 'new' script.
