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 :) ChrisA
