I'm aware of the functions and I've seen minimal usage examples on
stackexchange. I'll try again later.

Original code is:

  mp_ps_print_nl(mp, "%%CreationDate: ");
  mp_ps_print_int(mp, round_unscaled(internal_value(mp_year)));
  mp_ps_print_char(mp, '.');
  mp_ps_print_dd(mp, round_unscaled(internal_value(mp_month)));
  mp_ps_print_char(mp, '.');
  mp_ps_print_dd(mp, round_unscaled(internal_value(mp_day)));
  mp_ps_print_char(mp, ':');
  t = round_unscaled(internal_value(mp_time));
  mp_ps_print_dd(mp, t / 60);
  mp_ps_print_dd(mp, t % 60);

We'd have to calculate human readable time and then split it into 4
strings to populate the variables, if we want to do it right...
