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);
       }
