If that works, it looks like a (GNV?) extension, which doesn't show in
(GNV's) "--help"

$ pipe ls --help |search sys$pipe " -U"," -t"/exact
  -t                         sort by modification time, newest first
  -U                         do not sort; list entries in directory order
$

With GNV's

$ ls --version

-Ut doesn't seem to do the trick:

OK --full-time is much better, here
$ ls -t --full-time

As far as I know, ls knows about
* ctime (time of last status change): "-c     with -lt: sort by, and
show, ctime"
* mtime (time of last modification): "-t     sort by modification time,
newest first"
* atime (time of last access): "-u     with  -lt:  sort  by, and show,
access time"

It depends on the date mapping, which is used by GNV and/or the CRTL -
and maybe on the file system structure level, as ods5 can be initialized
with an "access date".

But maybe I'm missing something, it wouldn't be the first time :-)
