subtype: quarter.time_unit a unit of time equal to 15 minutes or a quarter of an hour; "it's a quarter til 4"; "a quarter after 4 o'clock"
subtype: second__s____sec 1/60 of a minute; the basic unit of time adopted under the System International d'Unites
subtype: leap_second a second (as measured by an atomic clock) added to or subtracted from Greenwich Mean Time in order to compensate for slowing in the Earth's rotation

subtype: time_duration any measure of length of time, with or without respect to the universal timeline

subtype: date
subtype: time_position any time_point or time_interval along the universal timeline from negative_infinity to positive_infinity
subtype: time_interval a time_interval has both an extent and a location on the universal timeline; a time_interval has no gaps, i.e. this class contains only convex time intervals
subtype: Day
subtype: Week
subtype: Month
subtype: Year
subtype: time_point the time_points at which processes occur can be known with various degrees of precision and approximation, but conceptually time_points are point-like and not interval-like; that is, it doesn't make sense to talk about how long a time_point lasts
subtype: Calendar-Date a point in time
subtype: physical_region__PR e.g., 2 meters, 3.5 kg, [2-3] hz
subtype: space_region__spaceregion__S
subtype: volume
subtype: abstract_region__AR e.g., 2 US dollars
subtype: function_quantity_type function that maps from one or more instances of constant_quantity to another instance of constant_quantity; for example, the velocity of a particle would be represented by a function_quantity mapping values of time (which are constant_quantities) to values of distance (also constant_quantities); note that all instances of function_quantity are functions with a fixed arity; note too that all elements of the range of a function_quantity have the same physical dimension as the function_quantity itself
subtype: unary_constant_function_quantity_type unary function that maps from sumo#constant_quantity to the same class
subtype: time_dependent_quantity_type a unary_constant_function of continuous time; all instances of this class map a time quantity into another constant_quantity such as temperature; for example, 'the temperature at the top of the Empire State Building' is a time_dependent_quantity since its value depends on the time
subtype: calorie
subtype: British_thermal_unit
subtype: constant_quantity physical_quantity with a constant value, e.g., 3 meters and 5 hours; the magnitude (see magnitude_fn) of every constant_quantity is a real_number; constant_quantities are expressed with measure_fn, e.g., 3 meters can be expressed as (sumo#measure_fn 3 meter); they form a partial order with the less_than relation, since less_than is a relation_extended_to_quantities and less_than is defined over the real_numbers; the less_than relation is not a total order over the class constant_quantity since elements of some subclasses of constant_quantity (such as length quantities) are incomparable to elements of other subclasses of constant_quantity (such as mass quantities)
subtype: time_measure
subtype: temporal_quality__TQ e.g., a date or a duration, but not its measure/value
subtype: Temporal_location__TL
subtype: temporal_region__TR a value for a temporal quality, e.g., 24/5/2002, 2 seconds
