Thanks for the suggestion. INRIM is clearly more reliable than the 
sources we were using, so I adjusted our tables to match INRIM's via the 
attached patch, which is installed in the development repository now.

If you have the time, could you ask INRIM two followup questions? My 
guess is that they'll prefer Italian-language questions and answers (and 
I am not lucky enough to speak Italian).

First, do their tables reflect Italian legal time, or the time that was 
observed on the ground in Rome? The difference might matter during the 
period of German occupation of Rome, roughly from 1943-09-10 to 1944-06-04.

Second, our commentary says "Sicily and Sardinia each had their own time 
zones from 1866 to 1893, called Palermo Time (+00:53:28) and Cagliari 
Time (+00:36:32)." Does INRIM have any information about legal time in 
Italy before 1916? I would prefer INRIM to Shanks as our source for this 
sort of commentary.

Thanks.
