During the experiment of 1968-1971, when the British Isles did not revert to Greenwich Mean Time during the winter, the all-year British Summer Time was called British Standard Time (BST). In the UK, UTC+0 is disseminated to the general public in winter and UTC+1 in summer. BBC radio stations broadcast the "six pips" of the Greenwich Time Signal. It is named from its original generation at the Royal Greenwich Observatory, is aligned to Coordinated Universal Time, and called either Greenwich Mean Time or British Summer Time as appropriate for
Greenwich Time Signal broadcast at 15:00 on Saturdays and at 10:00 and 11:00 on Sundays. This is caused by the scheduling of the afternoon play on Saturday and the omnibus edition of "The Archers" on Sunday. On BBC Radio 2, the pips are used at 07:00, 08:00, 17:00 and 19:00 on weekdays, at 07:00 and 08:00 on Saturdays and at 08:00 and 09:00 on Sundays. The pips were used on Radio 1 during "The Chris Moyles Show" at 06:30 just after the news, 09:00 as part of the Tedious Link feature, 10 am (at the end of the show) and often before "Newsbeat".
