'namespace' but is used like a 'type'

My program uses a class called Time2. I have the reference added to TimeTest but I keep getting the error, 'Time2' is a 'namespace' but is used like a 'type'.

Could someone please tell me what this error is and how to fix it?

    namespace TimeTest
    {
      class TimeTest
      {
        static void Main(string[] args)
        {
            Time2 t1 = new Time2();
        }
      }
    }
