Daylight savings time in the Magic Kingdom on March 14, 2010

I noticed an interesting situation for the operating hours of the Magic Kingdom on March 14, 2010. This day is the second Sunday in March is the day in the United States when daylight time begins. The operating hours are listed for the Magic Kindom on March 14, 2010 as:
  • Normal hours: 9:00 AM - 11:00 PM
  • Extra Magic evening hours: 11:00 PM - 2:00 AM
Due to the algorithm employed during parsing the dates, I have to determine that the 2:00 AM time listed for March 14, 2010 really means 2:00 AM early the next morning on March 15, 2010. But the date logic that I use knows that March 14, 2010 is the beginning of daylight time, which happens on March 14, 2010 AT 2:00 AM! So the date logic pushes the time component out to 3:00 AM. But then when I push the date over to the next morning on March 15, 2010, the duration of the extra magic hours is wrong because they are 11:00 PM - 3:00 AM, 4 hours. I will need to fix my logic to handle conversions during the date when daylight time starts. Once that is done, I will publish operating hours out past the beginning of March 2010.
