Local time is directly related to longitude due to the Earth’s rotation. As the Earth rotates 360 degrees in approximately 24 hours, each degree of longitude corresponds to a time difference of about four minutes. This means that locations east of a reference point (like the Prime Meridian) experience time ahead, while those to the west are behind. This relationship is important for timekeeping and navigation.
