date-command

[Anders.Persson]

 I´m running coreutils 6.9.92.4-f088d-dirty  (dirty??), and I found a bug. I´m 
using the function of asking for a date some month ago. For example date 
--date="-2 month" +%Y%m%d. And when doing that on the first o june 01:00, I got 
the answer march 31, instead of April 1. I´ve checked som alternatives, like 
using nn month ago, instead of a negative number of month. But the result is 
the same. I got the same result if I asked about 12 or 14 month ago, but not 13 
or 11 month ago. It seems like if I ask  for a number of month back, it should 
always be the first of a month, But it isn´t. It could be the 31 or 3 of a 
month. Obviously depending of the number of days in the  months. It doesn´t 
count a number of month backwords. But a number of days, not calculating 
correctly how many days the different days have.  It seems to happen on a even 
number of month back.

 This is my first bug-report, so I hope I reported in a good manner.
