CURLOPT_FILETIME(3)	   Library Functions Manual	   CURLOPT_FILETIME(3)

NAME
       CURLOPT_FILETIME	- get the modification time of the remote resource

SYNOPSIS
       #include	<curl/curl.h>

       CURLcode	curl_easy_setopt(CURL *handle, CURLOPT_FILETIME, long gettime);

DESCRIPTION
       Pass  a long. If	it is 1, libcurl attempts to get the modification time
       of the remote document in this operation. This requires that the	remote
       server sends the	time or	 replies  to  a	 time  querying	 command.  The
       curl_easy_getinfo(3)  function  with  the CURLINFO_FILETIME(3) argument
       can be used after a transfer to extract the received time (if any).

DEFAULT
       0

PROTOCOLS
       This functionality affects file,	ftp, http, sftp	and smb

EXAMPLE
       int main(void)
       {
	 CURL *curl = curl_easy_init();
	 if(curl) {
	   CURLcode res;
	   curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/path.html");
	   /* Ask for filetime */
	   curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
	   res = curl_easy_perform(curl);
	   if(CURLE_OK == res) {
	     long filetime;
	     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
