>From the man page:

-U     Use time when file was created for sorting or printing.

-u     Use time of last access, instead of time of last modification
of the file for sorting (-t) or printing (-l).

-t     Sort by descending time modified (most recently modified first). . . .

Does something like ls -Ult give you what you want? My interpretation
is that -u and -U need to be combined with -t or -l.

I think the -c option works the same way.
Did you get different output on a previous FreeBSD version?
