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);
       }
