Perhaps the most sensible thing to do -- both for gnuplot and for
Peter -- is to simply change the format to %Y. Gnuplot will, I assume,
interpret this as the literal year 68 (as in the first century),
and the user can add 1900 years (or 2000 years, or 1800, or whatever)
in the using statement. For data sets spanning a century division, a
(condition? true-cond : false-cond) will work in the using statement to
make the division.
