Why these exist
Time zones are political choices, not laws of nature. Countries pick an offset to match their geography, their trading partners, or simply to stand apart. Spain moved to Central European Time in 1940 to match Germany and never moved back. China unified its five pre-1949 zones into one to symbolize national unity. Kiribati and Samoa moved across the date line for business with Asia and Australia.
