PSCP supports two methods of performing file operations: SCP (the older
and simpler method) and SFTP (the newer method, which is used by default
if possible). When in SCP mode, "pscp -ls" just performs an "ls" command
on the server; scp_sftp_listdir() and SSH_FXP_OPENDIR is part of the
procedure for fetching a list of files with SFTP.
You can force a particular backend with the "-scp" and "-sftp" options;
if you use "-scp" (and the server supports your "--time-style" option)
you should find that your change becomes effective.

(Note that this is a much newer version of the protocol spec than PuTTY
supports, and cannot be used to fully understand the implementation in
PSCP/PSFTP due to protocol changes.)

No.
("pscp -ls" in SFTP mode uses the "longname" field returned by the SFTP
server, and there's no way of requesting a particular format for that;
there's no need, as if a particular field or format is required it is
returned in a machine-readable form alongside the textual "longname"
field, and can be output in whatever format is desired. We will probably
have to do this at some point in any case, as more recent versions of
the SFTP protocol have dropped the "longname" field.)
