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 1 jan 1970 in the  GMT/UTC
17       time  zone). If you get -1, it can be because of many reasons (it might
18       be unknown, the server might hide it or the server does not support the
19       command  that  tells document time etc) and the time of the document is
20       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);
