That does the trick, thanks.
I was trying to see how many uses of Wikidata qualifiers are contextual (i.e., give information about in which context the statement is valid) and which were additive (i.e., do not limit where the statement is valid).
Of the top ten qualifier properties by usage, five are contextual, three are additive, and one does not carry world information. The last can be considered to be contextual, but also might be considered to not carry world information.

I'm trying to get a good estimate of how often which qualifier predicate is used.
The obvious query times out, as expected, so I was trying to find a list of predicates that are used as qualifiers so that I can craft a query for each of them. There is https://www.wikidata.org/wiki/Wikidata:List_of_properties/Wikidata_qualifier but that can't be trusted as it doesn't include start time (P580) or end time (P582) which I expect to be the most common qualifier predicates.
So, I'm stumped. Any suggestions?
There is https://tools.wmflabs.org/sqid/#/browse?type=properties which might help you.
