This isn't a trick question is it?

ENGLAND - the answer is Loads and loads

So far, I've found thirteen:

-23:39 Belfast Time
-17 Truro Time
-13 Barrow Time
-11 Carnforth Time
-9 Liverpool Time
-7 Manchester Time
-6 Leeds Time
-5 Oxford Time
-3 Boston Time
+0 Greenwich Time
+7 Norwich Time
+14:10 Bristol Time
+30 Sandringham time (Edward VII said so)

Some places still show their defiance to the House of Commons and pooh-pooh their imposition of time:

The Bristol Corn Exchange:


There are two different minute hands showing both Greenwich Mean Time (in black) and Bristol Time.
