First, in the USA, Daylight Savings Time runs from the 2nd Sunday in Mach to the first Sunday in November. Your date of 12-23-2010 would be in Standard Time.
Second, the time of sunrise and sunset is very dependent on the date and exact location. A difference of 15 miles can change the time of sunrise or sunset by a minute. Please re-post your question with a city name or zip code.
You can easily calculate the time of sunrise or sunset by visiting the web site of the U.S. Naval Observatory at http://www.usno.navy.mil/USNO/astronomical-applications/data-services/rs-one-day-us.
