This has jogged my memory about a bug I discovered some time ago in the
libical time zone definitions. They were updated about a year ago by
Tepper Hasso. Many of the definitions are actually completely wrong in the
same manner as the new USA definitions. For example, Europe/London also
has only a single blanket definition starting in 1970, whereas the
previous (correct) version has many different definitions for different
years starting in the 19th century. The current version is wrong even for
some years post-1970. Tepper's commit needs to be reverted, and then the
new USA stuff needs to be added.
