Fixes #842

def _to_hours_mins_secs(time_taken: Union[float, int]) -> Tuple[int, int, int]:
    """Convert seconds to hours, mins, and seconds."""
    mins, secs = divmod(time_taken, 60)
    hours, mins = divmod(mins, 60)
    return round(hours), round(mins), round(secs)

Added round.

Description:

Check list:

• New tests are added (if a new feature is added)
