My original message is as follows:
"Hello all!

I received responses from several people, most of which said that I needed
to get my hands on the GNU version of ls which comes with it's own set of
source code. From there, I can modify the source code to get it to do what
ever I want.
I downloaded a whole set of utilities from
ftp://ftp.gnu.org/pub/gnu/fileutils-3.16.tar.gz
and here is the change that I made to ls.c:
if (full_time)
{
fmt = "%a %b %d %H:%M:%S %Y";
}
else
{
/* Added 08-18-98 StephenS */
/* fmt = "%b %e %Y"; */
fmt = "%d-%b-%Y";
/* if (current_time > when + 6L * 30L * 24L * 60L * 60L */ /*
Old. */
/* || current_time < when - 60L * 60L) */ /* In the
future. */
/* { */
/* The file is fairly old or in the future.
POSIX says the cutoff is 6 months old;
approximate this by 6*30 days.
Allow a 1 hour slop factor for what is considered "the future",
to allow for NFS server/client clock disagreement.
Show the year instead of the time of day. */
/* fmt = "%b %e %Y"; */
/* } */
/* else */
/* { */
/* fmt = "%b %e %H:%M"; */
/* } */
}
Now, the output of ls looks like this:
-rwxr-xr-x 1 sspaldin wcis 270336 18-Aug-1998 14:54 vdir
Thanks to all who responded!
