I confirm the bug (R-devel, Redhat 7.1)
To reproduce, it's sufficient to work with 
"%d %B" or "%d %b" .

What happens is that January and February work okay, and all
months from March produce the problem,


> strptime("28 Feb",format="%d %b")# ok
[1] "2002-02-28"
> strptime("19 March",format="%d %B")# wrong
[1] "2002-03-20"
