Is UK on GMT now
The United Kingdom uses Greenwich Mean Time (also known as Western European Time or UTC) and British Summer Time (UTC+01:00) (also known as Western European Summer Time).GMT is the standard time zone in Ireland and the United Kingdom, including England, Wales, Scotland, and Northern Ireland. All of these countries use DST during part of the year, but under different names. The United Kingdom and its Crown dependencies use British Summer Time during the DST period.The hour difference is because in the UK during summer the UK uses British Summer Time (BST) which is Greenwich Mean Time (GMT) plus one hour. That time change/difference is only apparent in the period April to October after which London and the UK reverts to GMT for the remainder of the year.
The time changes were widely advertised in the press. To return to GMT on 1st October 1916, people were advised to put their clocks forward by 11 hours rather than turning the hands back an hour, as in those days this would break the mechanism.
Why is GMT in London : There were two main reasons for this. The first was that the USA had already chosen Greenwich as the basis for its own national time zone system. The second was that in the late 19th century, 72% of the world's commerce depended on sea-charts which used Greenwich as the Prime Meridian.
Why is UK not on GMT : British Summer time (BST) is kept an hour head of Greenwich Mean Time (GMT) in the last Sunday in March to the last Sunday in October, all changes taking place at 01.00 GMT. GMT is regarded as daylight saving (giving more daylight during waking hours) in the winter, so why not continue to use GMT in the summer.

Is Germany one hour ahead of GMT : There is a 1 hour difference between the UK and Germany, with Germany (on CET – Central European Time) one hour ahead of the UK on GMT.
