+.TH CURLINFO_FILETIME 3 "28 Aug 2015" "libcurl 7.44.0" "curl_easy_getinfo options"
+.SH NAME
+CURLINFO_FILETIME \- get the remote time of the retrieved document
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
+.SH DESCRIPTION
+Pass a pointer to a long to receive the remote time of the retrieved document
+(in number of seconds since 1 jan 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 doesn't support the command that tells document time
+etc) and the time of the document is unknown.
+
+You must tell libcurl to collect this information before the transfer is made,
+by using the \fICURLOPT_FILETIME(3)\fP option to \fIcurl_easy_setopt(3)\fP or
+you will unconditionally get a -1 back.
+
+Consider using \fICURLINFO_FILETIME_T(3)\fP to be able to extract dates beyond
+the year 2038 on systems using 32 bit longs.
+.SH PROTOCOLS
+HTTP(S), FTP(S), SFTP
+.SH EXAMPLE
+.nf
+curl = curl_easy_init();
+if(curl) {
+  curl_easy_setopt(curl, CURLOPT_URL, url);
+  /* Ask for filetime */
+  curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
+  res = curl_easy_perform(curl);
+  if(CURLE_OK == res) {
+    res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
+    if((CURLE_OK == res) && (filetime >= 0)) {
+      time_t file_time = (time_t)filetime;
+      printf("filetime %s: %s", filename, ctime(&file_time));
+    }
+  }
+  /* always cleanup */
+  curl_easy_cleanup(curl);
+}
