What is an ival ?
(defn intersects? [ivals interval]
(not-empty (intersection ivals [interval]))) 2020-07-13T05:31:31.193900Z
ivals
refset 2020-07-13T08:23:17.194100Z
the example on the docs shows:
(t/intersects? [(t/year)]
(t/inc (t/year))) 2020-07-13T14:43:18.194300Z
Doesn't seem like intersects? works with a non-interval....
=> t4
#time/zoned-date-time "2020-07-04T00:00-07:00[US/Pacific]"
=> ti
#:tick{:beginning #time/zoned-date-time "2020-07-04T00:00-07:00[US/Pacific]", :end #time/zoned-date-time "2020-07-05T00:00-07:00[US/Pacific]"}
=> (t/intersects? t4 ti)
Execution error (UnsupportedOperationException) at tick.interval/assert-proper-head (interval.cljc:427).
nth not supported on this type: ZonedDateTimerefset 2020-07-13T15:00:18.194500Z
comparing with the reference code I posted, what happens when you add a vector in there (t/intersects? [t4] ti)

Not sure how to interpret this:
=> (t/intersects? [t4] ti)
nil 2020-07-13T17:46:28.194900Z
Also:
=> (t/intersects? [ti] ti)
(#:tick{:beginning #time/zoned-date-time "2020-07-04T00:00-07:00[US/Pacific]", :end #time/zoned-date-time "2020-07-05T00:00-07:00[US/Pacific]"}) 2020-07-13T17:47:17.195100Z
I question the use of the question mark at the end of this function name 🙂

The tick versions of >= etc are variadic just like clojure.core's, so your within? function could just be:
(t/<= (t/beginning i) time (t/end i))
