I'm not sure how important it is for the comments to be "legally
correct", other than when directly quoting the laws. And ±N doesn't seem
to me to be *more* "legally correct", it's just less readable to no
clear purpose.

Are there any countries whose law still prescribes the time zone as a
meridian (that may be a multiple of 15, but arguably still can't be
"legally correctly" described as GMT±N since it gives the difference in
degrees rather than hours), e.g. "the mean solar time of the sixtieth
degree of longitude west from Greenwich"? The US law doesn't currently,
but I can't find when it changed.
