We've made a number of changes in our copies, unfortunately. What you
have to do is look at the upstream diffs since we last synchronized
with them (which according to src/timezone/README was tzcode 2010c)
and merge those diffs as appropriate. It should be reasonably
mechanical, but don't forget to update the README.
