Am I correct to think there is no Year Zero in any event?
You are correct.
The Romans had no zero as it had not yet been invented, hence the first

Quite right, of course, though I was commenting on you can relax after your
Christmas dinner in the knowledge that your new watch will be telling the same
time as your sundial.
As ever, a pleasure to read your comments.

There's Press release at:

It also gives an email for the Heritage Manager and asks you to make contact

You could give it a try.
