In case you're interested, I've now tested our code pretty thoroughly
against tzcode2001a (in RedHat Linux 7.1), and that was the only error I

The test program stepped from 1970 to 2037 every 15 minutes, and
converted the UTC time to local time and back, comparing the local times
against mktime(). It did this for all the timezones that used city
names, e.g. 'Europe/London' - we don't use stuff like 'Etc/GMT-1'.
