RE: Time Ontology: Smallest possible increment-of-time

Thanks Bart, Christof -

I have put an additional example in the Temporal Precision section which shows use of fractional seconds (milliseconds).

I'll close ISSUE-157.

Hi,

I had exactly the same observation as Pascal, including the same revelation that xsd:decimal actually allows fractions.
This was also my comment on a earlier request for review [1]

I've created ISSUE-157 to add a example with fragments to the specification

Hello *,

what's the smallest duration of time one can specifiy with the proposed time
ontology? I wonder if it's really a full "second"? (Couldn't find anything
smaller but may have missed it).

Analog to spatial ontology, where you can define very (indefinitely?) small
spatial dimensions, this should be also possible within the time ontology.

If you would allow 'https://www.w3.org/TR/xmlschema11-2/#nt-seFrag' (instead of
xsd:decimal) as datatype for time:second you wouldn't even need tons of new
properties to be able to be arbitrarily precise.

If it's too nice for one to always assume decimal numbers when hitting
time:second I would propose one new time:TemporalUnit property (say:
time:secondFrag) which would suffice to define every time(t), where "t < 1s".
