NAME

6       CURLINFO_FILETIME - get the remote time of the retrieved document
7

SYNOPSIS

9       #include <curl/curl.h>
10
11       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
12

DESCRIPTION

14       Pass  a  pointer  to a long to receive the remote time of the retrieved
15       document (in number of seconds since 1 jan 1970  in  the  GMT/UTC  time
16       zone).  If  you  get -1, it can be because of many reasons (it might be
17       unknown, the server might hide it or the server does  not  support  the
18       command  that  tells document time etc) and the time of the document is
19       unknown.
20
21       You must tell libcurl to collect this information before  the  transfer
22       is made, by using the CURLOPT_FILETIME(3) option to curl_easy_setopt(3)
23       or you will unconditionally get a -1 back.
24
25       Consider using CURLINFO_FILETIME_T(3) to be able to extract  dates  be‐
26       yond the year 2038 on systems using 32 bit longs.

EXAMPLE

32       curl = curl_easy_init();
33       if(curl) {
34         curl_easy_setopt(curl, CURLOPT_URL, url);
35         /* Ask for filetime */
36         curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
37         res = curl_easy_perform(curl);
38         if(CURLE_OK == res) {
39           res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
40           if((CURLE_OK == res) && (filetime >= 0)) {
41             time_t file_time = (time_t)filetime;
42             printf("filetime %s: %s", filename, ctime(&file_time));
43           }
44         }
45         /* always cleanup */
46         curl_easy_cleanup(curl);
