Sillyfolkboy added a comment to T145532: HH:MM:SS time in Wikidata (new datatype or display option for quantity datatype?) .

On the point of precision, just read the detail at https://www.wikidata.org/wiki/Special:ListDatatypes#Time. If possible we will need precision up to a hundredth of a second (e.g. 800 metres world record is 1:40.91). Precision only up to tenths of a second (e.g. 9.2 seconds) is also a very common usage for historic hand-timed data - electronic timing only became more widespread from 1970 onwards.

I have been discussing known issues of this data type with the webmaster at Association of Road Racing Statisticians and he has raised a point about needing precision. For example, if only the hours are known rather than the seconds, then that "03:00:00" would be different from "03:00:00" measured to the second. I'm presuming we can cater for that distinction with a precision qualifier, rather than needing to account for that at base level?

The proposal is not for expressing time-of-day, it is to express a duration. Durations do not have time zones.

What if the duration is more than 24 hours? Should the quantity allow durations greater that 24 hours to be expressed as w days, x hours, y minutes, z seconds?
