New Zealand officially adopts a standard time

Background. Standard time involves synchronising clocks within a geographical region to a single standard rather than local mean time. New Zealand's adoption in 1868 preceded the global application of time zones in the 20th century. Separately, in 1868 the Telegraph Department adopted 'Wellington time' as the standard time across all its offices, so that opening and closing times could be synchronised.

Official Adoption. On 2 November 1868, New Zealand officially adopted a standard time to be observed nationally. It was the first country in the world to establish a nationwide standard time, achieving this status about fifteen years before any other nation. This event marked a significant step in the synchronisation of time standards.

Telegraph Operations. In 1868, the Telegraph Department adopted 'Wellington time' as the standard time across all their offices. This measure was implemented so that opening and closing times could be synchronised. The supplied passages state this adoption and its purpose but do not specify its timing relative to the national adoption of 2 November 1868.
