Post-quantum standards and timelines
Use this section when you have a government date, a customer question, or a vendor claim, and you need to know whose clock it is.
The pages here do not tell you how to configure a protocol. Dates carries the UK, EU, and NIST clocks that this edition can cite. Migration guides is the reading list, including the Dutch handbook, which this book does not rewrite. Country names and agency names stay on those pages. They are not the navigation of the site.
Handbook guidance: a date belongs to you when you are in that jurisdiction or you sell into it. The next action is an inventory, on Where to start.
