Besides post-processing results, you can also instruct java.jdbc to return
Joda dates in the first place.
Using clojure.java.jdbc 0.3.0-alpha4:
(ns example
(:require [clojure.java.jdbc :as j]
[clj-time.local :as cl]))
...
(extend-protocol j/IResultSetReadColumn
java.sql.Date
(result-set-read-column [date]
(cl/to-local-date-time date)))
Note that result-set-read-column's signature has changed in master; you'll
need to update it to [date _ _] in the next release.
