thx neil for the superfast reply! i just figured it out a few minutes ago and was coming to report my findings. :D here's what i did: (date->string (string->date "February 12, 2011" "~B ~d, ~Y") "~Y-~m-~d") but i'll turn it into a function as you have done, of course. this stuff below is a new encounter: > (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) my son helped me understand what it was doing after we looked check-expect up. so this runs a function for you and checks to see that the result is really what you say it is going to be! that's pretty useful, so a second thx! -- in friendship, prad _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
