Merge?
edittime interval (Q14646051) seems to be a duplicate of this item. Should we merge it? I put a link to this question at the other item and the Wikidata:Project chat. To get some of the editors involved: @TomT0m: @Laddo: @A.Bernhard:. Multichill (talk) 10:56, 3 May 2014 (UTC)
- As I said in project chat, there is the same distinction as a vector an a segment in geometry : one is a duration, 1 second, 1 month, the other is a segment of time (a range : during the Neolithic). I can't remember which is which

interval
edit@Infovarius: If a time interval is an interval in math years, months, days and seconds are mathemtical objects. Also embryogenesis, ancient history, eternity, 40-hour week, Cold War (1947–53), half-time, vacances. Please think about it. Bigbossfarin (talk) 15:28, 5 December 2017 (UTC)
- I am ok with this. They are all intervals along time dimension which have begins and ends. --Infovarius (talk) 20:36, 9 December 2017 (UTC)
- ...is a group of years, year is a group of months, month is a group of days, day is a group of hours, hour is a group of minutes, minute is a group of seconds, seconds is a sequence of events. --Fractaler (talk) 08:22, 11 December 2017 (UTC)
Superset
editNow: temporal entity (temporal entity (Q26907166), "thing that can be contained within a period of time, or change in state (e.g. events, periods, acts)". So, time interval (Q186081) (time interval) is "thing that can be contained within a period of time, or change in state (e.g. events, periods, acts)"? --Fractaler (talk) 12:14, 7 December 2017 (UTC)
Physical quantity
editHi. Now an then the statement time interval (Q186081)subclass of (P279)physical quantity (Q107715) has been added. I argue that this is not correct: A time internal, following the current (English) description, is a composite object, having three parts: A start, an end, and consequently a length/duration. The latter is indeed a (physical) quantity, but this does not make the whole time internal a quantity. An analogy: A bike has a mass, and mass is a physical quantity. But that does not make a bike a physical quantity. Toni 001 (talk) 11:23, 12 February 2020 (UTC)
- Hm, strange interpretation... Do you think that duration has neither start nor end? --Infovarius (talk) 19:07, 13 February 2020 (UTC)
- Correct. If someone says: "The duration was 2 hours" then we don't know yet when the event started or ended. So duration is only one aspect of a time interval. If instead someone says "the year 1980" then we know that they mean something with a duration of one year, starting on the first of January 1980 and ending on the 31st of December 1980.
