https://github.com/techascent/tech.ml.dataset/commit/bd8dacb2b75241791b6695d763d8b0ebc91b3106 Agreed that's an improvement, I still think examples would go a long way. I'll put the `good first issue` tag on here and some enthusiast will come and do...

Here is a more minimal repro, and a workaround: ```clj user> (require '[tech.v3.dataset :as ds]) nil user> (import 'java.time.Instant) java.time.Instant user> (def ds (ds/->dataset {:x (range 5) :y (repeatedly 5...

:+1: - nice, thanks! Could be a good bug.

:+1: Thanks for the heads up!

For sure instants are supported: ```clj user> (->> (for [idx (range 10)] {:a idx :b (.plus (java.time.Instant/now) (java.time.Period/ofDays idx))}) (ds/->>dataset)) _unnamed [10 2]: | :a | :b | |---:|-----------------------------| |...

Hi. The nix stuff is contributions from @craig-latacora and @thenonameguy, perhaps they'd have some opinion. Since there are apparently many ways to do this, I wonder if it makes sense...

This is a great question. What have you tried? This is the first thing that I think of: ```clj user> (def _ (add-lib 'org.scicloj/noj)) #'user/_ user> (require '[tech.v3.dataset :as ds])...

Is a `Column` really `Associative`? ```clj user> (def _ (add-lib 'org.scicloj/noj)) #'user/_ user> (def _ (add-lib 'io.github.tonsky/clojure-plus)) #'user/_ user> (require '[tech.v3.dataset :as ds]) nil user> (def ds (ds/->dataset {:x [1...
