CURLINFO_FILETIME(3)	   Library Functions Manual	  CURLINFO_FILETIME(3)

NAME
       CURLINFO_FILETIME - get the 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
       document	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 un-
       known, the server might hide it or the server does not support the com-
       mand  that tells	document time etc) and the time	of the document	is un-
       known.

       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 be-
       yond 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 res;
	   curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
	   /* Ask for filetime */
	   curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
	   res = curl_easy_perform(curl);
	   if(CURLE_OK == res) {
	     long filetime = 0;
	     res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
	     if((CURLE_OK == res) && (filetime >= 0)) {
	       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,
