Time for another clarification. Since nseconds is unsigned, then mike's 'interpreted as negative' could only mean that nseconds should be subtracted from seconds when seconds are negative. So how do you represent a number between 0 and -1 second? (-1 seconds) - (any positive nseconds) is always more negative then (-1 seconds) Which won't work. Therefore, since nseconds is unsigned, then it must always be added to seconds. For example, -1ns would be seconds = -1, and nseconds = 999,999,999
