Predicate for when something is a date time type about clojure.java-time HOT 5 CLOSED

do I understand correctly that you have data with org.joda.time.Instant/org.joda.time.DateTime fields inside which you want to serialize into ISO8601 strings?

Haven't actually noticed Inst before. Your solution would definitely work. It has an additional benefit of not transforming the datastructure just to change the type of instants. Also, there shouldn't be any problems with globally extending Inst for DateTime as in Joda-Time it is analogous to an Instant.

I don't think there's anything in this project that can help you do what you want to do in a more direct way.

Yeah, my problem is fully solved by this piece of code, but perhaps it'd be good to add this to the portability code here so it automatically works for everyone :)

It might make more sense in clj-time instead?

Hmm, I think adding

(extend-type org.joda.time.ReadableInstant
     Inst (inst-ms* [inst] (.getMillis inst)))

shouldn't break anything. However, a library shouldn't be extending foreign types with foreign protocols. This may have a place in an explicitly invoked method or documentation though.

Added a when-joda-time-loaded macro to the public API. Updated docs.

Cool, thanks :) I look forward to using this feature in a new release.
