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

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

PROTOCOLS

       This functionality affects 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);
         }
       }
