Nautical time communicating with land, the land time zone must be employed. The nautical time zone system is an ideal form of the terrestrial time zone system for use on high seas. Under the system time changes are required for changes of longitude in one-hour steps. The one-hour step corresponds to a time zone width of 15° longitude.

A nautical date line is implied but not explicitly drawn on
