     and what should it set its value to, should there be optional constructors
     say allowing only an time_durations that generate a time from a clock,etc.
     So, in fact multiple time types can be created for a time_system with
     different construction policies, and all of them can perform basic
-    operations by only writing a copy constructor.  Finally, compiler 
-    errors are also shorter.

     The real behavior of the time class is provided by the time_system
     template parameter.  This class must provide all the logic
     for addition, subtraction, as well as define all the interface
     types.
