NAME

6       CURLINFO_FILETIME - get the remote time of the retrieved document

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 January 1 1970 in the GMT/UTC  time
16       zone. If you get -1, it can be because of many reasons (it might be un‐
17       known, the server might hide it or the server does not support the com‐
18       mand  that tells document time etc) and the time of the document is un‐
19       known.
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);
