I second this -- we actively use the database for *all* dates, including those pre-1970 because historical financial information extends back to 1895 in some cases. There is no other database that captures this data accurately. If the IANA tz database is shrugging off all the work that went into making this database what it is, we'll have no choice but to fork it.
