In the *compilation* buffer, we see timestamps when the compilation
started and finished.  It would be nice to also see how long the
compilation command took.  The attached patch does that.  It looks like
this:

  Compilation finished at Sat Aug 12 20:23:57, 2.52s

Subject: [PATCH] When a compilation finishes, show how long it took

Insert the duration, not just the timestamp.

* lisp/progmodes/compile.el (compilation--start-time): New variable.
(compilation-start): Set it.
(compilation-handle-exit): Use it to compute the duration and
 insert it in human readable form.
