     18 # NAME
     19 
     20 CURLINFO_FILETIME_T - get the remote time of the retrieved document
     21 
     22 # SYNOPSIS
     23 
     24 ~~~c
     25 #include <curl/curl.h>
     26 
     27 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME_T,
     28                            curl_off_t *timep);

     31 # DESCRIPTION
     32 
     33 Pass a pointer to a curl_off_t to receive the remote time of the retrieved
     34 document in number of seconds since January 1 1970 in the GMT/UTC time zone.
     35 If you get -1, it can be because of many reasons (it might be unknown, the
     36 server might hide it or the server does not support the command that tells
     37 document time etc) and the time of the document is unknown.
     38 
     39 You must ask libcurl to collect this information before the transfer is made,
     40 by using the CURLOPT_FILETIME(3) option or you unconditionally get a -1 back.
     41 
     42 This option is an alternative to CURLINFO_FILETIME(3) to allow systems with 32
     43 bit long variables to extract dates outside of the 32-bit timestamp range.

     58     res = curl_easy_perform(curl);

     61       res = curl_easy_getinfo(curl, CURLINFO_FILETIME_T, &filetime);
     62       if((CURLE_OK == res) && (filetime >= 0)) {
     63         time_t file_time = (time_t)filetime;
     64         printf("filetime: %s", ctime(&file_time));

     75 # RETURN VALUE
     76 
     77 curl_easy_getinfo(3) returns a CURLcode indicating success or error.
     78 
     79 CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
     80 libcurl-errors(3).
