MDTM command falsely implemented?

[KewlSokudo]

No matter which FTP client I use, the MDTM command just doesn't work and spits a 502 response at me. Probably because it isn't actually a feature of ftpd? It's listed in the README.md and even some strings in the source code mention it:

void FtpSession::HELP (char const *args_) { setState (State::COMMAND, false, false); sendResponse ("214-\r\n" "The following commands are recognized\r\n" " ABOR ALLO APPE CDUP CWD DELE FEAT HELP LIST MDTM MKD MLSD MLST MODE\r\n" " NLST NOOP OPTS PASS PASV PORT PWD QUIT REST RETR RMD RNFR RNTO SITE\r\n" " SIZE STAT STOR STOU STRU SYST TYPE USER XCUP XCWD XMKD XPWD XRMD\r\n" "214 End\r\n"); }

But there isn't any actual working code for it in ftpSession.cpp What's with this?

There is no API on the 3DS or Switch to be able to set a file's timestamp, and so therefore the MDTM is impossible to implement.
