supertype: dl#entity a category from DOLCE or generalized by a category from DOLCE
subtype: dl#stative__STV as opposed to eventive occurrences, the sum of two stative occurences is the same kind of occurrence, e.g., the sum of 2 sittings is a sitting
subtype: dl#state__ST stative occurence with all its parts being the same kind of stative occurrence, e.g., sitting, being red
subtype: dl#process__proces__pro eventive occurence with some parts not being the same kind of stative occurrence, e.g., running, writing
subtype: dl#event__EV as opposed to stative occurrences, the sum of two eventive occurences is not the same kind of occurrence
subtype: dl#achievement__ACH atomic eventive occurence, e.g., reaching a summit, a departure, a death
subtype: dl#accomplishment__ACC non atomic eventive occurence, e.g., a conference, an ascent, a performance
subtype: dl#region__R the measure of an attribute/dimension
subtype: dl#temporal_region__TR a value for a temporal quality, e.g., 24/5/2002, 2 seconds
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__mean_solar_day__twenty-four_hours__solar_day__solarday 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"
subtype: #night.time_unit the dark part of the diurnal cycle considered a time unit; "three nights later he collapsed"
subtype: #mean_time__mean_solar_time (astronomy) time based on the motion of the mean sun (an imaginary sun moving uniformly along the celestial equator)
subtype: #terrestrial_time__terrestrialtime__TT__terrestrial_dynamical_time__terrestrialdynamicaltime__TDT__ephemeris_time__ephemeristime (astronomy) a measure of time defined by Earth's orbital motion; terrestrial time is mean solar time corrected for the irregularities of the Earth's motions
subtype: #month a time unit of 30 days; "he was given a month to pay the bill"
subtype: #lunar_month__moon__lunation__synodic_month the period between successive new moons (29.531 days)
subtype: #anomalistic_month__anomalisticmonth period between successive perigees; approximately 27.5546 days
subtype: #sidereal_month period between successive conjunctions with a star, 27.322 days
subtype: #solar_month__solarmonth one-twelfth of a solar or tropical year
subtype: #sidereal_day__day the time for one complete rotation of the earth relative to a particular star, about 4 minutes shorter than a mean solar day
subtype: #ship's_bell__bell (nautical) each of the eight half-hour units of nautical time signaled by strokes of a ship's bell; eight bells signals 4:00, 8:00, or 12:00 o'clock, either a.m. or p.m.
subtype: #hour__hr__60_minutes a period of time equal to 1/24th of a day; "the job will take more than an hour"
subtype: #sidereal_hour 1/24 of a sidereal day
subtype: #man_hour__manhour__personhour a time unit used in industry for measuring work
subtype: #half-hour__30_minutes a half of an hour
subtype: #quarter-hour__quarterhour__15_minutes a quarter of an hour
subtype: #minute__min a unit of time equal to 60 seconds or 1/60th of an hour; "he ran a 4 minute mile"
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: #millisecond__msec one thousandth of a second
subtype: #attosecond one quintillionth of a second; one thousandth of a femtosecond
subtype: #femtosecond one quadrillionth of a second; one thousandth of a nanosecond
subtype: #picosecond one trillionth of a second; one thousandth of a nanosecond
subtype: #nanosecond one billionth of a second; one thousandth of a microsecond
subtype: #microsecond one millionth of a second; one thousandth of a millisecond

subtype: sumo#time_duration any measure of length of time, with or without respect to the universal timeline
instance: akts#twentyfour-hour-duration__24_hour_duration akts#seven-day-duration__sevendayduration__7_day_duration__7dayduration akts#twentyeight-day-duration__twentyeightdayduration__28_day_duration akts#twentynine-day-duration__29_day_duration akts#thirty-day-duration__30_day_duration akts#thirtyone-day-duration__thirtyonedayduration__31_day_duration akts#twelve-month-duration__12_month_duration
subtype: sumo#time_position any time_point or time_interval along the universal timeline from negative_infinity to positive_infinity
subtype: sumo#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: sumo#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: akts#Calendar-Date a point in time
subtype: dl#physical_region__PR e.g., 2 meters, 3.5 kg, [2-3] hz
subtype: dl#abstract_region__AR e.g., 2 US dollars
