How to add date to Recipe Title

Hello,

I have created a recipe to generate a Huffingtonpost.fr ebook, I then email it to my kindle 2nd generation.

My kindle only shows the latest issue and not the ones I produced in previous days, I believe it is an overwrite issue.

I thought about adding the date to the title of the huffingtopost.fr issue title so I would keep previous versions and I quickly identified when they were produced.

If you have a better idea about how to sort the problem (i.e. keeping more than an issue in the kindle), it is more than welcome.

I post my recipe below, my knowledge of coding is very very limited.

Thanks in advance

José
