Hi Jonathan

I'm using English.

In your test all the files have a similar modified time so you cannot 
see the difference. However, in my example, you can see that the widths 
for date and hour are not zero-padded so the width can be either 1 or 2.

French is even worse

smk     1149 8 avr. 2012 16:03:20 bin/vbin/netbeans
smk      170 20 nov. 2009 16:47:42 bin/vbin/syncdown
smk      671 8 févr. 2012 20:11:22 bin/vbin/ssh.desktop
smk      187 20 nov. 2009 16:47:34 bin/vbin/syncsf

So here even the width of month abbr can be different.

Thanks
Max
