Looks like a bug to me, then again, Spetember didn't have 31 days! I get the
same answer if I ask it to go back to any month with 28, 29, or 30 days in it!
[REW: This discussion was held "behind the scenes", and I didn't
believe it until I realized that this was "date" related (I had to put
my date back on my computer to reproduce this). It is security related
if you use this date command to e.g. select a set of files to be
backed up or removed.... Anyway, I'd want the date command to give me
either the closest guess or no output on stdout and an error on
stderr....]
