Get difference between DateTime instances with clj-time

I am trying to calculate the difference between two DateTime instances using clj-time. I looked through the documentation and found clj-time.core/minus and clj-time.core/minus- but both require an instance of org.joda.time.ReadablePeriod and not one of DateTime. I would prefer to use cli-time, but if no solution exists, what would be the cleanest method of calculating the delta using Joda Time?

Thank you for the help.

I use this snippet very often in my daily work: 

(ns project.namespace1
  (:require [clj-time
              [core :as t]] )

(let [start-time (t/now)]
  ... do lots of work ...
  (t/in-millis (t/interval start-time (t/now))))
