>>Not odd at all. On railway timetables, the midnight is 24:00 if it's an arrival time (so this leg of the train's trip ends within the same day) and 0:00 if it's a departure time (so the whole trip is again in the same day).

>It is also a commom trick if you have to clculate working times, accommodation allowance and the likes. And, what means 64kiB adressable? Do you realy had 64k available? I can't belive this ....

Not everything that is addressable is deliverable. You can write an address on your inner tyre, the post office still won't take it until you take it off the wheel, pack it and address the package.

Update: how does one address a forest? By "dear trees", or by writing street, number, zip code and city on each tree?
