About these time zones
Greenwich Mean Time (GMT)
Greenwich Mean Time (GMT) is the time at UTC+0. GMT and UTC show the same clock time; UTC is the scientific standard, while GMT is a time zone name. The United Kingdom and Ireland use GMT only in winter: in summer the UK switches to British Summer Time (BST, UTC+1) and Ireland to Irish Standard Time (IST, UTC+1).
Central European Time (CET)
Central European Time (CET) is UTC+1, the standard time of most of the European Union from Spain to Poland. From the last Sunday in March to the last Sunday in October those countries use Central European Summer Time (CEST, UTC+2). Algeria and Tunisia stay on UTC+1 all year.
