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 ac5bf8cfce67cdb5662aeea618c2eb9511f0d190, reversing changes made to 5a8a49a8c77d6d5ba0f46f0e5b51dec2daba46db.
