A controversy about the handling of the Time Zone Database (tzdb) has
been brewing since May, but has come to a head in recent weeks.
Changes that were proposed to simplify the main database file have some
consequences in terms of time-zone history and changes to the
representation of some zones. Those changes have upset a number of users
of the database—to the point where some have called for a fork. A
September 25 release of tzdb with some, but not
all, of the changes seems unlikely to resolve the conflict.
