Ok. I start work :-)

It's an arbitrary choice I made when I wrote the code :-I  It's not 
POSIX I'm afraid.

I certainly wouldn't object to -V doing the same as -v but rounding 
down this could also decide how to behave when a -v adjusts the 
time onto a non-existent time (say 1:30 when the clocks go forward).

I'm pink, therefore I'm spam.

date(1) and -v-1m

[Alexander Langer]

Hello!

The behaviour of date(1) is probably specified by POSIX, but I think,
date -v-1m should at least return a date a month _before_ the current
month.

Example:
Mi   1 Dez 1999 15:06:47 CET

(Dez. has 31, so it should be Nov 30, I think).

More confusing is something like:
alex:~ $ date -v-1m +%Y-%m
1999-12

what I wanted to use to create backup folders for my mail-system (all
mails of the last month are moved to a folder of the last month).

That's weird, somehow.

Is this a bug or a feature?
Is this POSIX-compilant?

Do we want an additional option? (I want :-))
