CURLINFO_FILETIME(3)					     curl_easy_getinfo options					      CURLINFO_FILETIME(3)

NAME

       CURLINFO_FILETIME - get the remote time of the retrieved document

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);

DESCRIPTION

       Pass  a	pointer  to a long to receive the remote time of the retrieved document (in number of seconds since 1 jan 1970 in the GMT/UTC time
       zone). If you get -1, it can be because of many reasons (it might be unknown, the server might hide it or the server  doesn't  support  the
       command that tells document time etc) and the time of the document is unknown.

       Note  that  you	must  tell  the server to collect this information before the transfer is made, by using the CURLOPT_FILETIME(3) option to
       curl_easy_setopt(3) or you will unconditionally get a -1 back.

PROTOCOLS

       HTTP(S), FTP(S), SFTP

EXAMPLE

       curl = curl_easy_init();
       if(curl) {
	 curl_easy_setopt(curl, CURLOPT_URL, url);
	 /* Ask for filetime */
	 curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
	 res = curl_easy_perform(curl);
	 if(CURLE_OK == res) {
	   res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
	   if((CURLE_OK == res) && (filetime >= 0)) {
	     time_t file_time = (time_t)filetime;
	     printf("filetime %s: %s", filename, ctime(&file_time));
	   }
	 }
	 /* always cleanup */
	 curl_easy_cleanup(curl);
       }
