Autoblog date placeholder not working

Hello,

For Autoblog, I’m using the ‘Append Text to Post’ add on and the place holders are not working for providing a date, both %POSTIMPORTEDTIME% %ORIGINALPOSTGUID%

The %ORIGINALPOSTGUID% provides a sting of numbers that is a date (just not very good looking) and the other is just random numbers. Anything I can add to get a nice looking date of with the post was either published or imported?

Thanks,

JS
