//! Representation of a precise moment in time, including the date.
  /*! 
    This class is a skeleton for the interface of a temporal type
    with a resolution that is higher than a day.  It is intended that 
    this class be the base class and that the actual time 
    class be derived using the BN pattern.  In this way, the derived 
    class can make decisions such as 'should there be a default constructor' 
    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.
