is there a function which will convert
"February 12, 2011"
to
"2011-02-12"
Racket search turns up "string->date" and "date->string". You can use
them to define your new procedure like this...
;;;; BEGIN
#lang racket/base
(require srfi/19)
(define (us-long-date-str->iso-8601-date-str long-date-str)
(date->string (string->date long-date-str
"~B ~d, ~Y")
"~Y-~m-~d"))
(require test-engine/racket-tests)
(check-expect (us-long-date-str->iso-8601-date-str "February 12, 2011")
"2011-02-12")
(check-expect (us-long-date-str->iso-8601-date-str "February 09, 2011")
"2011-02-09")
(check-expect (us-long-date-str->iso-8601-date-str "February 9, 2011")
"2011-02-09")
(test)
;;;; END
