Does it still think your location is Iceland if you manually clear the cookies (again) and revisit the site?

I have tried a manual Clear Data (using the Everything setting in When) but it has made no difference. Oddly even on a clean power up/browser start there is 1.2MB of temporary cached files/pages and I cannot identify what is creating that since I have removed all websites from any exceptions and my other laptop with apparently the same settings shows 77kb.

I am presuming it thinks I am in Iceland but the site which showed the location was for the Rugby World Cup which has now finished. The Formula1.com site and the Cricinfo sites show 'My Time' as the same one hour different.

That's weird, I'm not sure why the website would still be showing your old location. Here are a few questions I would like to ask for more information: Does the website still use the same time zone if you view it in a new Firefox profile? What about a different browser? Do you have this issue with other websites not on your exception list? I suspect that this could be an example of browser fingerprinting, where websites can identify users based on characteristics of the users' software and hardware without needing IP or cookies from previous sessions.
