I would make minute offsets mandatory, because we are discussing not only
contemporary but historical time zone data, when minute offsets were more
common. Also IMHO minute offsets are not necessarily a Bad Thing; a small
country without any of its territory going through an hourly meridian but with
territory going through a minute offset might be better served by the minute
offset zone; Portugal and Ireland, for example, fit GMT-0:30 closer than GMT
What I would favor is putting a colon in between hours and minutes, for
readability; i.e. the time in Darwin, Australia is easier to read as GMT or
UT+09:30 than as +0930.
