Oh! I have it. Gretl is considering 1700 as a leap year, when it is not
so. The exact centuries are only leap years when they are a multiple of 400.

?Are we sure that gretl is treating correctly the leap year in the
gregorian calendar? I think that 146097 days should be exactly 400
years, but but when I try to define such a dataset, the last observation
is december 30. There is a day missing. (gretl from git on Ubuntu 16.04,
built on january 26)
