Unfortunately the zoneinfo files are compiled into a binary format
for faster lookup, but for real fun, you can have a look at the
sources from which they are generated.  If you have the glibc source
tree unpacked, look into the timezone subdirectory.

There you can see problems discussed like when Alaska switched from
the Julian to the Gregorian calendar, which time zones were used when
on what Antarctican base, and how to represent a peculiar Saudi Arabian
time zone that adjusts the clock every day so that noon always agrees
with the apparent solar noon ;-)
