In order to avoid properties throwing exceptions, maybe is wise
to impose getters and setters to be nothrow.

Why? Because code like this (C#) seems a bit unnatural:

try{

myClock.Hours   = 28;  /* setter throws exception because 28 is
an invalid hour value */
myClock.Minutes = 15;
myClock.Seconds = 39;

}catch(InvalidTimeValueException itve){

/* figure out which field was invalid and report error */

}
