CURLINFO_FILETIME(3)       Library Functions Manual       CURLINFO_FILETIME(3)

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 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 tell libcurl to collect this information before the transfer
       is made, by using the CURLOPT_FILETIME(3) option to curl_easy_setopt(3)
       or you this unconditionally gets a -1 back.

       Consider using CURLINFO_FILETIME_T(3) to be able to extract dates
       beyond the year 2038 on systems using 32 bit longs (Windows).

PROTOCOLS
       FTP, HTTP and SFTP

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
           /* Ask for filetime */
           curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
           res = curl_easy_perform(curl);
           if(CURLE_OK == res) {
             long filetime = 0;
             res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
             if((CURLE_OK == res) && (filetime >= 0)) {
               time_t file_time = (time_t)filetime;
               printf("filetime: %s", ctime(&file_time));
             }
           }
           /* always cleanup */
           curl_easy_cleanup(curl);
         }
       }
