<Tr> <Th> Time zone </Th> <Td> Greenwich Mean Time (UTC) </Td> </Tr> <Tr> <Th> Summer (DST) </Th> <Td> British Summer Time (UTC + 1) </Td> </Tr> <P> Greater Manchester is a metropolitan county in North West England, with a population of 2.8 million . It encompasses one of the largest metropolitan areas in the United Kingdom and comprises ten metropolitan boroughs: Bolton, Bury, Oldham, Rochdale, Stockport, Tameside, Trafford, Wigan, and the cities of Manchester and Salford . Greater Manchester was created on 1 April 1974 as a result of the Local Government Act 1972; and designated a City Region on 1 April 2011 . </P> <P> Greater Manchester spans 493 square miles (1,277 km), which roughly covers the territory of the Greater Manchester Built - up Area, the second most populous urban area in the UK . It is landlocked and borders Cheshire (to the south - west and south), Derbyshire (to the south - east), West Yorkshire (to the north - east), Lancashire (to the north) and Merseyside (to the west). There is a mix of high - density urban areas, suburbs, semi-rural and rural locations in Greater Manchester, but land use is mostly urban--the product of concentric urbanisation and industrialisation which occurred mostly during the 19th century when the region flourished as the global centre of the cotton industry . It has a focused central business district, formed by Manchester city centre and the adjoining parts of Salford and Trafford, but Greater Manchester is also a polycentric county with ten metropolitan districts, each of which has at least one major town centre and outlying suburbs . </P>
