(def image-processing-time (timer "image-processing-time"))
+You can also use the ``deftimer`` macro to create a timer and bind it to a var
+in one concise, easy step::
+ (use '[metrics.timers :only (deftimer)])
+ (deftimer image-processing-time)
+All the ``def[metric]`` macros do some :ref:`magic <desugaring>` to the metric
+title to make it easier to define.
