That was the point. We can abolish codepages by using Unicode, which
covers everything. We could abolish time messes by having every
locality settle permanently on one timezone; Ben's theory demands that
all timezones be some integer number of hours +/- UTC, which IMO is
optional, but mainly it should be easy to figure out any two
locations' difference: just subtract one's UTC offset from the
other's. Similarly, you can calculate the difference between two times
at the same location by simple subtraction; currently, you also have
to consider the possibility of a DST switch (from noon to noon across
a switch is either 23 or 25 hours).

Actually, the nearest parallel to Unicode is probably "use UTC
everywhere", which makes for a superb internal representation and
transmission format, but bugs most human beings :)
