Convert Clojure #inst instant in time to Joda time with clj-time

Question

What is the right way to parse Clojure time instants like #inst "2017-01-01T12:00:00" to Joda time using the clj-time library?

Answer 1

If you have a java.util.Date object:

(type #inst "2017-01-01T12:00:00+02:00")
;;=> java.util.Date

clj-time has a clj-time.coerce namespace with a from-date function that takes java.util.Date objects as input. Example:

(require '[clj-time.coerce :as c])

((juxt type str) (c/from-date #inst "2017-01-01T12:00:00"))
;;=> [org.joda.time.DateTime "2017-01-01T12:00:00.000Z"]

Answer 2

Also clj-time now provides a data-reader to automatically coerce dates in EDN to/from joda datetimes: clj-time EDN support

(clojure.edn/read-string {:readers clj-time.coerce/data-readers}
                         "#clj-time/date-time \"2019-07-10T06:00:00.000Z\"")
==>
#clj-time/date-time "2019-07-10T06:00:00.000Z"
