I am a little concerned about performance but since I am only looping through only about 20 (maybe 30 in the future) items, either way (DateTime or Timespan) would be very fast. But I will go with Timespan because it is more efficient.
Thank you.

>>Thank you for your help. I didn't know you can use TimeSpan type with assigning only hours, minutes, seconds. Examples of TimeSpan I saw always set it to a difference between two datetime values. But your example definetely works. I will have to decide whether to use TimeSpan or DateTime, as Perry suggested. My guess is that TimeSpan should be faster as it stores only the hours whereas DateTime has a longer value.
