Hmmm, I just tried it again and it seems to work:
perl -MDate::Calc -MData::Dumper -e "print Dumper(\Date::Calc::Add_Delta_YMD(2001,1,29,0,+1,0));" and it printed: 
$VAR1 = \2001;
$VAR2 = \2;
$VAR3 = \28;

I tried it several different ways and all of them seemed to work now. Maybe the author of Date::Calc saw my post, wrote a fix, hacked my box and replaced by buggy module with a new version!

Or maybe I didn't test it properly before I posted.

Well, as far as Date::Calc is concerned (if we are to believe it) we should truncate it down to Feb 28th.

I don't quite feel at ease about this, but my world view is now secure again - I can say with confidence the exact date in one month's time!
