15 Pass a pointer to a curl_off_t to receive the remote time of the re‐
16 trieved document (in number of seconds since 1 jan 1970 in the GMT/UTC
17 time zone). If you get -1, it can be because of many reasons (it might
18 be unknown, the server might hide it or the server does not support the
19 command that tells document time etc) and the time of the document is
20 unknown.
21
22 You must ask libcurl to collect this information before the transfer is
23 made, by using the CURLOPT_FILETIME(3) option to curl_easy_setopt(3) or
24 you will unconditionally get a -1 back.
25
26 This option is an alternative to CURLINFO_FILETIME(3) to allow systems
27 with 32 bit long variables to extract dates outside of the 32bit time‐
28 stamp range.
