[local-time-devel] Endless loop (or something similar) in adjust-timestamp

Hi folks,

By accident, I found that the following never returns (well, at least
here; my timezone is GMT+3, running SBCL 1.0.44.36):

(local-time:adjust-timestamp (local-time:encode-timestamp 0 0 0 3 11 4
2010 :offset (* 3 3600)) (offset :day -14))

This seems to fix it and looks correct, though I can't be sure about it:

diff -rN -u old-local-time/src/local-time.lisp
new-local-time/src/local-time.lisp

     (cond
-      ((> start end)
+      ((>= start end)
        (if (minusp end)

Other ideas?
