OK, so it's been 12 hours with no further discussion, so I'll make an attempt to summarize what I think is the consensus changes before updating the PEP.

  1. Python will include a timezone database both in the source distribution and the Windows installer (although I suspect that binary packages for Linux distributions may skip this, but that's OK).

  2. The timezone module becomes datetime.timezone, meaning datetime.py is moved to datetime/init.py

  3. get_timezone() will be just timezone() as no voices was raised to defend get_timezone()

  4. The db parameter in timezone() will be renamed db_path

  5. is_dst will default to False

  6. The UnknownTimeZoneError exception will be just a ValueError

  7. The two errors raised when converting timezones will both inherit from a base exception.

  8. A better name for the timezone data package. "tzdata-override" was suggested, I prefer "tzdata-update" as it is clearer.
