But the Ferro meridian was established in 1634. So there are several
counter claims on who was 'first' ...

It is this area that wy own interests lie, and it is not clear from the
limited data provided on James Gregory if his meridian was actually
associated with setting time anywhere other than St. Andrew? Just what
was the spread of usage of common time across the UK back in the 17th
