So, as you see, the problem is in parse-time-string.  I'm not even
sure that function is supposed to be able to parse the output of %c,
since on my system that produces an obviously bogus result:

 (format-time-string "%c" (current-time)) => "8/10/2015 8:41:41 PM"

but

 (parse-time-string "8/10/2015 8:41:41 PM") => (41 41 8 8 nil 2010 nil nil nil)

Look, ma: no month! and the year is off!

However,

 (current-time-string) => "Mon Aug 10 20:44:52 2015"

and

 (parse-time-string "Mon Aug 10 20:44:52 2015") => (52 44 20 10 8 2015 1 nil 
nil)

as expected.
