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.

In response to public dissent, the Prime Minister announced that the clock change would, officially, take effect from Thursday 2023-03-30 00:00; however, as many who resisted the original change had already moved their clocks forward from Sunday 2023-03-26 00:00, tzdata has modeled this as a simple reversion of the change released in 2023b.

This change, announced by the Prime Minister on just over two days' notice, was met with fierce opposition and was actively resisted by a significant portion of the general public. After a few days, the Prime Minister relented, which was reflected in 2023c.
