If those actually require 3 (or more) chars (letters perhaps, but then +07
wouldn't work) then change the quidelines.   It is that simple.   There is
no reason for such a restriction - and what's more, we should be able to
create zones which reflect the "military" zone names (A B C ... Z, missing
just I I think it is, but it has been a while) which are all 1 char long
(but are unable to represent offsets that aren't an even number of hours).

See attached:

Juliet                   is localtime;
Zulu                     is GMT;
Alpha..Mike             are GMT+1..12;
November..Yankee        are GMT-1..12.

I used to add them under .../ITU, but now under .../Etc, including spelling variations Alfa, Juliett, Whiskey (I'm Scottish/Irish), X-ray, and single letters.
