[tz] Rules for TZ+ database

[David Patte ₯]

There are family homes, and restaurants in northern Vermont / southern 
Quebec that have the national boundary line (and hense the tz region) 
running through the middle of the buildings. (Rock Island Qc/Vt, for 
example) This is not a big tz issue now since both Montreal & New York 
follow similiar rules, but it certaily must have been confusing in the 
1990s for a few years when their dst rules were different!

 From Wikipedia:

The Tomifobia River <http://en.wikipedia.org/wiki/Tomifobia_River> runs 
through the town of Stanstead, dividing the U.S./Canadian border at 
times. Along portions of Canada's Canusa Street 
<http://en.wikipedia.org/wiki/Canusa_Street>, houses on the southern end 
of the street lie entirely within Vermont, while their driveways direct 
northward, and connect to the street in Quebec, as the northern portions 
of their properties are within Canada. These residents' backyard 
neighbours are American, while families living right across the street 
are Canadian, though no noticeable boundary exists between the two (the 
street itself is entirely within Canada). In other places, the 
international border runs through individual homes, so that meals 
prepared in one country are eaten in the other. An entire tool-and-die 
factory, once operated by the Butterfield division of Litton Industries 
<http://en.wikipedia.org/wiki/Litton_Industries>, is also divided in two 
by the border.^[16]
