Many people are getting ready for daylight-saving time to end this week. Clark's 8-year-old daughter will probably be much harder to get out of bed in the mornings for school. She must take after her father, who admits to having seasonal-affective disorder (SAD). The switch back to standard time will take place across the nation -- except in Arizona, Hawaii, throughout the Navajo Nation, Puerto Rico, the Virgin Islands, Guam and a select few other spots. The reason for the annual time change is to save energy by having extra daylight time. That's because people use less energy in the early evening hours. Clark thinks it's interesting that our clock is controlled by economics. He probably needs to be a two hemisphere kind of guy -- he should move to South America during the winter to take advantage of their opposite seasons! There is one person who is even more affected by the time change than Clark -- that's Mike, the husband of Clark's executive producer Christa. When daylight-saving time ends on Nov. 4, he'll say we're entering "The Tunnel." If you're wondering why daylight-saving time was pushed back a week this year, it's so that kids across the country could do their early Halloween trick-or-treating in sunlight. One word of caution to all drivers: Dusk is the most difficult time to see children in the streets.
