--- Comment #6 from Michael Kay <mike@saxonica.com> ---
Having slight difficulty working out how best to say this in a way that
actually tells people that a tzoffset of 130 means one hour and 30 minutes,
without relying on the reader's common sense, or at the other extreme treating
them like idiots...
The production rule is
tzoffset ::= ("+"|"-") hours ":"? minutes?
where
hours ::= digit digit?
minutes ::= digit digit
So assuming people know how to parse from BNF, I think the best way would be to
refer to the parts of the production rule:
"If a @tzoffset@ is supplied then @hours@ supplies the hours part of the
timezone offset, and @minutes@, which defaults to zero if absent, supplies the
minutes part."
That's dangerously close to being tautological but I think the font changes
make clear the distinction between syntactic components of the supplied string
and semantic components of the resulting value.
