when we originally pulled this data out in london we did
zdump -v `find /usr/share/zoneinfo/ -type f -print`
(well, more or less, it seems like there is also
/usr/share/zoneinfo/right and /usr/share/zoneinfo/posix
which duplicates a lot of the data).
We then had a 3 or 4 line perl script to convert it to insert
statements. With the new "copy" format I think it should
be pretty easy to recreate the data.
