-1 implies that it's curl_easy_getinfo that is failing, not the sprintf.
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).
