Give it a number of seconds and it answers in six registers at once: the breakdown into days, hours, minutes and seconds; the same thing spelled out in words; an ISO-8601 duration; a clock-style HH:MM:SS that wraps at 24 hours the way a clock does; and a table placing the duration against minutes, hours, eight-hour work days, forty-hour work weeks and Julian years of 365.25 days. Fractions are carried on the smallest unit instead of being rounded away, and a negative duration keeps its sign once, in front of the whole value.
One number in seconds, six ways out. The clock wraps at 24 hours by design — it is a clock reading, not a duration — while the unit table keeps carrying into days, weeks and Julian years. Fractions stay on the smallest unit rather than being rounded away, and a negative input carries its sign once, in front, instead of negating every field.
