tzdata-meta

The metadata compiled herewithin is secondary to the tz repository and is derived from the archives of the tz discussion list as well as commits to the tz development repository. Metadata is limited to changes affecting UTC offsets for current and/or future timestamps at the time that notice is sent. Pull requests will NOT be accepted for a given timezone change until it has been proposed to the tz mailing list at tz@iana.org, discussed as necessary, been committed to the tz development repository, and (in general) released.
