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 January 1 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);
       }
