show only the month of the publisched date

Hi everybody,
I want to show in a chunk only the month of the pub_date. Searching in the web, I find only this script:
[[*createdon:strtotime:date=`%B`]]
I've trying to change "createdon" with "publishedon", but doesn't give me a result.

I also ask y where I can change the language of the dates, from en to italian.

Thanks in advance.

First: Dont mix up pub_date and publishedon; see
http://bobsguides.com/published-on-publish-date-confusion.html
for details.

Second: The value of publishedon for a freshly created resource is 0.
It will get a different value only in the case that

• there is a set pub_date
• and the pub_date lies in the past (at the moment of the request of the resource)

I just found:gives an empty output.

But when you insert a blank before %B, it works:
Someone around here able to explain this?
