NAME

6       CURLINFO_FILETIME_T - 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_T,
12                                  curl_off_t *timep);
13

DESCRIPTION

15       Pass  a  pointer  to a curl_off_t to receive the remote time of the re‐
16       trieved document in number of seconds  since  January  1  1970  in  the
17       GMT/UTC time zone. If you get -1, it can be because of many reasons (it
18       might be unknown, the server might hide it or the server does not  sup‐
19       port the command that tells document time etc) and the time of the doc‐
20       ument is unknown.
21
22       You must ask libcurl to collect this information before the transfer is
23       made, by using the CURLOPT_FILETIME(3) option to curl_easy_setopt(3) or
24       you will unconditionally get a -1 back.
25
26       This option is an alternative to CURLINFO_FILETIME(3) to allow  systems
27       with  32 bit long variables to extract dates outside of the 32bit time‐
28       stamp range.

EXAMPLE

34       curl = curl_easy_init();
35       if(curl) {
36         curl_easy_setopt(curl, CURLOPT_URL, url);
37         /* Ask for filetime */
38         curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
39         res = curl_easy_perform(curl);
40         if(CURLE_OK == res) {
41           curl_off_t filetime;
42           res = curl_easy_getinfo(curl, CURLINFO_FILETIME_T, &filetime);
43           if((CURLE_OK == res) && (filetime >= 0)) {
44             time_t file_time = (time_t)filetime;
45             printf("filetime %s: %s", filename, ctime(&file_time));
46           }
47         }
48         /* always cleanup */
49         curl_easy_cleanup(curl);
