Half-second ties round upward. Hours do not wrap at 24; this is a duration format rather than a wall clock.
How the calculation works
Round non-negative total seconds, then split into unbounded hours, minutes and seconds. Half-second ties round upward. Hours do not wrap at 24; this is a duration format rather than a wall clock. Counts and dimensions use the declared rounding convention; other numbers display up to three decimal places where applicable. Nonzero subsecond durations are labelled. Durations round to the nearest second; nonzero subsecond durations are labelled. File-size output units are decimal. Changing an input label does not convert filled values.
Example
Worked example: Total Seconds = 3661. Result: 01:01:01.
Practical tip
Check the input labels and assumptions against the seconds to hh:mm:ss task before reusing the number.
