Strange things happen to time when you travel, because the earth is divided into twenty- four time zones, one hour apart. You can have days with more or fewer than twenty- four hours, and weeks with more or fewer than seven days. If you make a five- day trip across the Atlantic Ocean, your ship enters a different time zone every day. As you enter each zone, the time changes one hour. Traveling West, you set your clock back; traveling East, you set it ahead. Each day of your trip has either twenty - five or twenty - three hours
