伦敦时间几时区？
“London，UK” means different things to different people. Is it the city of London？ Yes， but not just as it is now (though it has always been a major settlement) – because if you go back ten thousand years or so you’ll find the settlements that are now central London were then out in open country on the north bank of the Thames - no canals or bridges then， let alone skyscrapers and tube stations… But they had a castle at Westminster and a monastery at Southwark， two landmarks which still exist today despite being on the south side of the river. And so “London， UK” meant for centuries any settlement between those two places where English was spoken.
In the nineteenth century this started to change with large parts of London reverting to countryside， and new buildings springing up all over the old city (the City of London）as well as outside its walls， especially eastwards towards Whitechapel.
The boundary of the county borough of London (now just the City of London) was fixed in law by Statute in 1963， and has remained unchanged ever since. It is defined as： “The area within a circle with a radius of one mile from Point 0， which is near St Paul's Cathedral （the actual building， not the church as an historical monument）and whose centre is marked by an iron pillar beneath the dome of what used to be a railway terminus called "King's Cross".” The boundary is therefore a very small part of Greater London， although most people are unaware of this fact. In fact， only about twenty per cent of Londoners live inside the boundary of the ancient Borough of London， the rest living outside， mostly to the north and East into neighbouring boroughs such as Barnet， Brent， Redbridge， Ealing等等. Despite these changes， “Londinium” has stuck， and today we mean “London” when we say Londinium.
I am a bit unsure why there are questions like this around！ As I said before， anyone born here would know that “London” means whatever you want it to mean， depending on context. There may have been an age of uncertainty in which nobody really knew what “London” meant， but that ended many centuries ago. Perhaps someone is writing a history of how language evolves， in which case they need to clarify whether meanings are determined by social factors such
