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).

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);
         }
       }
