Re: [h-e-w] Odd dired date format

[Geert Ribbers]

Hi.

The function that arranges this is copied below.
There is no way to influence this behavior (other than overwriting the
function in your .emacs), it's hardcoded.
It would probably be a good idea if the authors would introduce a
custom-variable for it (authors copied).

I always regarded this as a feature!  Older files show
the year.  If the file is less than 6 months old, the
time is shown, as a time distinction may be relevant
for recent files.

No doubt the 6-month limit occurs somewhere as an
explicit parameter.
