  subtype:  pm#unit_of_time_duration  the class of all unit of measures used to measure time, e.g., minute, second, hour, etc.
     subtype:  #time_unit__unit_of_time  a unit for measuring time periods
        subtype:  #day__meansolarday__twenty-four_hours__solar_day  time for Earth to make a complete rotation on its axis; "two days later they left"; "they put on two performances every day"; "there are 30,000 passengers per day"
