ok, this was suprising from juxt/interval
(t/new-interval (t/date "2020-01-01")
(t/date "2020-01-02"))
#:tick{:beginning #time/date-time "2020-01-01T00:00", :end #time/date-time "2020-01-03T00:00"}
I didn't expect the end time to have the date of the next day
which makes using t/relation a bit tricky
The end is exclusive.
Or I think it is based on that
