I'd write that up and send it to the module's author. Sounds buggy to me. At the very least, it should return an error code that there is no Feb 29th. On a more Perlish level, it should try and 'do the right thing'.

My personal opinion on the 'right thing' is that +1 month refers to the next month, so wrapping Feb 29th (non-leap year) to March 1st seems wrong. (I would have a differnt feeling for adding a month worth of days.) But truncating it down to Feb 28th also seems wrong. Perhaps an error code is the best result.

But in any case, let the author know. Sounds like they didn't come across that condition, so never checked for it. Feedback is important to keeping the quality of modules high.
