CURLINFO_FILETIME(3)       curl_easy_getinfo options      CURLINFO_FILETIME(3)

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 doesn't
       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 _FILETIME&section=3">CURLOPT_FILETIME(3) option to _easy_setopt&section=3">curl_easy_setopt(3) or
       you will unconditionally get a -1 back.

       This option is an alternative to _FILETIME&section=3">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);
       }
