You can still see clocks in the UK from the late 19th century which have two minute hands: one for the local time and the other for the official Greenwich time.

The Bristol Exchange has a big one with the hands ten minutes apart, since that's the difference between local noon in Bristol and noon at Greenwich.

Supposedly in Oxford you can still be 5 minutes and 2 seconds "late" for classes or meetings since that's the offset between there and Greenwich. I've only heard this third-hand - are there are any Oxonians out there who can confirm?
