This time difference is called Time Span (System.TimeSpan structure) and is calculated, not to much of surprise, using '−' operator. I hardly can understand how could you miss it. It could be like this:

C#

System.DateTime login = System.DateTime.Now;

// remember this point ...

// some time later
System.DateTime logout = System.DateTime.Now;

System.TimeSpan timeSpan = logout - login;
// and so on

I cannot see why would you need a DateTimePicker here, but if you need, it also has the value of System.DateTime. Conceptually, there is no date and time, there is only time. Only you should not work with members of these structures separately. They have everything to calculate what you need.
