CURLINFO_FILETIME(3)	    Library Functions Manual	    CURLINFO_FILETIME(3)

NAME
     CURLINFO_FILETIME - remote time of the retrieved document

SYNOPSIS
     #include <curl/curl.h>

     CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);

DESCRIPTION
     Pass  a pointer to a long to receive the remote time of the retrieved docu-
     ment in number of seconds since January 1 1970 in the GMT/UTC time zone. If
     you get -1, it can be because of many reasons (it	might  be  unknown,  the
     server  might hide it or the server does not support the command that tells
     document time etc) and the time of the document is unknown.

     You must ask libcurl to collect this information  before  the  transfer  is
     made,  by using the CURLOPT_FILETIME(3) option or you unconditionally get a
     -1 back.

     Consider CURLINFO_FILETIME_T(3) instead to be able to extract dates  beyond
     the year 2038 on systems using 32-bit longs (Windows).

PROTOCOLS
     This functionality affects ftp, http and sftp

EXAMPLE
     int main(void)
     {
       CURL *curl = curl_easy_init();
       if(curl) {
	 CURLcode result;
	 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
	 /* Ask for filetime */
	 curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
	 result = curl_easy_perform(curl);
	 if(result == CURLE_OK) {
	   long filetime = 0;
	   result = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
	   if((result == CURLE_OK) && (filetime != -1)) {
	     time_t file_time = (time_t)filetime;
	     printf("filetime: %s", ctime(&file_time));
	   }
	 }
	 /* always cleanup */
	 curl_easy_cleanup(curl);
       }
     }

AVAILABILITY
     Added in curl 7.5

RETURN VALUE
     curl_easy_getinfo(3) returns a CURLcode indicating success or error.

     CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
     libcurl-errors(3).
