- make DEFAULT sections less repetitive - make historic mentions use HISTORY - generate the protocols section on `# %PROTOCOLS%` instead of guessing where to put it - generate the availability section on `# %AVAILABILITY%` instead of guessing where to put it - make the protocols section more verbose Closes #14227

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 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 CURLOPT_FILETIME(3) option or you unconditionally get a -1 back.
Consider CURLINFO_FILETIME_T(3) instead to be able to extract dates beyond the year 2038 on systems using 32-bit longs (Windows).

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);
}
}

RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
