another example of use might be checking if the current time falls in a range:

static void Main(string[] args)
{
TimeRange timeRange = new TimeRange();
timeRange = TimeRange.Parse(”13:00-14:00″);

bool IsNowInTheRange = timeRange.IsIn(DateTime.Now.TimeOfDay);
Console.Write(IsNowInTheRange);

Console.ReadLine();
}
