Hey Julian,
See this thread for some ideas.
Create New Text File in Finder
I've changed my copy of the script in post #6 to create new text files from scratch, so the creation and modification dates match when the file was created.
I've left the dates of the other template files alone, so they reflect when the template was created/modified – although it wouldn't be too hard to update these to NOW() (when the "new" file is created) – and that might be the better choice for some users.
