I think you've answered your own question: you SHOULD use private types for
Time_Type and Delta_Time_Type. That way, not only do you get the control
over operations that you need, you also get an explicit statement of unit
for all your literals! E.g., T+15.0 is poor software engineering compared
to T+Seconds(15.0), although you might prefer T+Duration(15.0) at a pinch.
