The DST code has not yet been fully tested, the upcoming movement refactor is upon us and it will integrate with the micro timezone library anyway. Revert it so that next can be merged into main. This reverts commit 3c86a42aa83356735be2bd84b7027b156e8d3a2c, reversing changes made to be969c4deb144280b59d0293cc45dc3443b096cf.
