In addition to clj-time, I tend to use -> with date-clj as well:
(-> (today)
(subtract 30 :days))
And I find something like this:
(->> (-> response :body :postalCodes)
(map to-location) (sort-by :city))
much easier to read than:
(sort-by :city (map to-location (:postalCodes (:body response))))
YMMV tho'...
