     18 # NAME
     19 
     20 CURLINFO_FILETIME - 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, long *timep);
     28 ~~~

     30 # DESCRIPTION
     31 
     32 Pass a pointer to a long to receive the remote time of the retrieved document
     33 in number of seconds since January 1 1970 in the GMT/UTC time zone. If you get
     34 -1, it can be because of many reasons (it might be unknown, the server might
     35 hide it or the server does not support the command that tells document time
     36 etc) and the time of the document is unknown.
     37 
     38 You must ask libcurl to collect this information before the transfer is made,
     39 by using the CURLOPT_FILETIME(3) option or you unconditionally get a -1 back.
     40 
     41 Consider CURLINFO_FILETIME_T(3) instead to be able to extract dates beyond the
     42 year 2038 on systems using 32-bit longs (Windows).

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