24:
25: .SH NAME
26: CURLINFO_FILETIME \- get the remote time of the retrieved document
27: .SH SYNOPSIS
28: #include <curl/curl.h>
29:
30: CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
31: .SH DESCRIPTION
32: Pass a pointer to a long to receive the remote time of the retrieved document
33: (in number of seconds since 1 jan 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 doesn't support the command that tells document time
36: etc) and the time of the document is unknown.
37:
38: You must tell libcurl to collect this information before the transfer is made,
39: by using the \fICURLOPT_FILETIME(3)\fP option to \fIcurl_easy_setopt(3)\fP or
40: you will unconditionally get a -1 back.
41:
42: Consider using \fICURLINFO_FILETIME_T(3)\fP to be able to extract dates beyond
43: the year 2038 on systems using 32 bit longs.
44: .SH PROTOCOLS
45: HTTP(S), FTP(S), SFTP
46: .SH EXAMPLE
47: .nf
48: curl = curl_easy_init();

51: /* Ask for filetime */
52: curl_easy_setopt(curl, CURLOPT_FILETIME, 1L);
53: res = curl_easy_perform(curl);
54: if(CURLE_OK == res) {
55: res = curl_easy_getinfo(curl, CURLINFO_FILETIME, &filetime);
56: if((CURLE_OK == res) && (filetime >= 0)) {
57: time_t file_time = (time_t)filetime;
58: printf("filetime %s: %s", filename, ctime(&file_time));
59: }
