[racket] SRFI 19 string->date: Error reading dates

Hi all,

I’m running into this problem with string->date in srfi/19:

;;; begin Interactions
> (require srfi/19)
> (string->date "Sun, 02 Feb 2015" "~a, ~d ~b ~Y”)
result arity mismatch;
expected number of values not received
 expected: 1
 received: 0
 values...:
;;; end Interactions

I’m assuming there’s something I am missing about how dates are handled, but from what I’ve read it seems like the code above should be doing it. What am I missing?

(And, is there a better way to be reading dates in Racket, or is this the preferred way?)

Best,
jmj

P.S. Attempting to copy/paste the above error message from the Interactions window crashed DrR (v6.1.1) three times. This doesn’t seem to be reproducible by copying any other error messages, though, so I haven’t filed a bug report yet; figured perhaps the answer to the string->date problem may shed some light on this, too...
