Time in Vinland is divided into four time zones. It uses Atlantic Time, Eastern Time, Midwestern Time, and Mountain Time. The adoption of time zones in Vinland on a major scale were in the mid-1700's, when trains first began to span the entirety of the nation. Originally, the entire east portion of Vinland used Eastern time, until the Atlantic time zone was split off in 1892. Daylight Savings Time was an important part of the Vinland time system until the mid-1930's, when it became more than unnecessary, even in the western provinces. Vinland, however, was still one of the last nations to abolish DST, and did so in 1986.
