.TH CURLINFO_FILETIME 3 "2025-06-27" libcurl
.SH NAME
CURLINFO_FILETIME \- get the remote time of the retrieved document
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_FILETIME, long *timep);
.fi
.SH 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 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 \fICURLOPT_FILETIME(3)\fP option or you unconditionally get a \-1 back.
Consider \fICURLINFO_FILETIME_T(3)\fP instead to be able to extract dates beyond the
year 2038 on systems using 32\-bit longs (Windows).
.SH PROTOCOLS
This functionality affects ftp, http and sftp
.SH EXAMPLE
.nf
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);
}
}
.fi
.SH AVAILABILITY
Added in curl 7.5
.SH RETURN VALUE
\fIcurl_easy_getinfo(3)\fP returns a CURLcode indicating success or error.
CURLE_OK (0) means everything was OK, non\-zero means an error occurred, see
\fIlibcurl\-errors(3)\fP.
