Date stamp in a template

I’m trying to set a date variable for a template so that once the template is used to create a new document the date is populated with the current date.

That's easy to achieve:

  1. Open the template or document you wish to serve as template.
  2. Choose Insert > Date and choose the Type "Document creation date" (and the Format). Then press the Insert button. 
  3. Choose File > Save as template... and save the document where you wish it saved. 

That's it. From now on, when opening this template, the creation date will be stamped in the document. You can, of course, choose where to place this stamp and how to style it.
