But (as my base class shows) implementing the required API using only the
tm_isdst flag and the timezone-related attributes of the time module
(tzname, timezone, altzone) a satisfactory implementation can be obtained,
and that API has been stable since the beginning of time. (Well, at least
since 1993: https://hg.python.org/cpython-fullhistory/rev/6ee380349c84 .)
