-------------------------------------------------+-------------------------
 When dividing time_duration by a 64-bit integer the divisor will be
 implicitly cast to 'int' type (32-bits on most platforms).

 This will cause 'division by zero' runtime error for any value which is a
 multiple of 2^32^.
 It will also cause invalid values to be calculated if the divisor is
 larger than 2^31^ - 1.

 I don't see any reason why the time_duration interface should be limited
 to division by 32-bit integer values on systems where the storage type
 used in time_duration is at least 64-bit long.
