How to auto download bookmarks?

I have 100’s of bookmarks saved in a DTPO folder.

I want to automate DTPO to download the bookmark pages and save them all (rich text or PDF) at a regular intervals and save them in a separate time stamped folder. What should I do?

You could e.g. install the additional script “Convert URLs to PDFs” (see Scripts > More Scripts…). Afterwards just select the bookmarks and run this script. Time stamped groups will require some customization of the script though.
