The reasons for this can include things like (a) the web server doesn't support it, and (b) you didn't use curl_easy_setopt to specify beforehand to get the information (see http://curl.haxx.se/libcurl/c/curl_easy_getinfo.html#CURLINFOFILETIME).

That was it! The url was not valid. Thanks for helping me understand where the error was coming from.
