NAME

       CURLINFO_FILETIME_T - get the remote time of the retrieved document

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME_T,
                                  curl_off_t *timep);

DESCRIPTION

       Pass a pointer to a curl_off_t 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 does not support the command that tells document time
       etc) and the time of the document is unknown.

       You  must  ask  libcurl  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.

       This  option  is  an  alternative  to CURLINFO_FILETIME(3) to allow systems with 32 bit long variables to
       extract dates outside of the 32bit timestamp range.

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) {
           curl_off_t filetime;
           res = curl_easy_getinfo(curl, CURLINFO_FILETIME_T, &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);
       }
