- Create a folder Classes/ViewHelpers/Format in the extension
- Put a file DateViewHelper.php in that folder
- Copy the content of the file below in there, and change Tx_Something to your needs
- Add the following to your Fluid template: {namespace ext=Tx_Something_ViewHelpers} (of course change Tx_Something here too)
- Show a date using {item.datetime -> ext:format.date(format:'%e %B %Y')}
