 Dear Steve

 Thanks for proposing this correction. Perhaps I overlooked earlier that
 udunits.dat (my copy of it, anyway), defines year=tropical_year. So that
 means udunits defines a year as 3.15569259747e7 seconds. It's awkward to
 convert this number into days! udunits defines a day as 86400 seconds
 exactly. So we have to divide 3.15569259747e7 by 86400 with 12 digits of
 precision. I can't get it to equal exactly what the existing text says,
 but it's not exactly 365.2425 either, because a year isn't a Gregorian
 year. Is your udunits the same?

 Cheers

 Jonathan
