In order to set delayed publish on a version it needs to be in the state "Ready to Publish". So after you chosen "Save and View" select "Ready to Publish" and the "Delayed Publish" option on the versions tab should be enabled.

That works, thanks very much!
I have a page that is currently published, I want to make a change to it but set a time that it will publish these changes.
I've made the change to my page and chosen to Save and View. On the "Versions" tab there is a "Delayed publish" icon next to my new version however it is not selectable. I've gone into Admin Mode and the "Publish delayed page versions" service is active and running.
How do I enable this Deplayed publish icon?
