Quo opera equatorius laborat? Quo instrumento equatorium resarcit?
It would seem that they can patch their equatorium by simply engraving
some new dates. Did they have resedit in the 1600's? [0]
In any case, such a UI patch should already have been performed: the
British didn't adopt the Gregorian Calendar until 1752, so the nominal
inputs should have been changed then. (temporalization? were there t13n [1]
consultants during the 16th-18th centuries?)

[0] it would appear so: "+resedit +Aeneid" shows that a resedit was
not unknown to Vergil.
[1] according to <http://shell.ihug.co.nz/~hermetic/cal_stud/cal_art.htm>,
T13N was quite the political process in old Rome:
>Another source of uncertainty regarding exact dating of days at this

>had 29 days and in leap years 30 days (unlike 28 and 29 now). It lost a

>calendar were renamed as Julius and Augustus respectively, in honor of
>their eponyms, and the number of days in August, previously 30, now
>became 31 (the same as the number of days in July), so that Augustus
>Caesar would not be regarded as inferior to Julius Caesar. The extra
>day needed for August was taken from the end of February. However there
>is still no certainty regarding these matters, so all dates prior
>to A.D. 8, when the Julian Calendar finally stabilized, are uncertain.

"tri via" ~= "three roads" ~= "crossroads" (well, Y rather than X),
because the gossip exchanged at crossroads is not important.
