Time zones

All week I've been getting off at Piccadilly Circus and passing this old map on the way to the exit.

I'd never noticed it until this week as I usually take another route out of the Tube station.

It includes the whole world with time calculations from Greenwich Mean Time.

Gene Kiegel, our course tutor talked to us today about his work and in honour of the Ukrainian who grew up in the States we all went for a Mexican at lunchtime.
