About these time zones
Australian Eastern Standard Time (AEST)
Australian Eastern Standard Time (AEST) is UTC+10. New South Wales, Victoria, Tasmania and the ACT use AEST in winter and Australian Eastern Daylight Time (AEDT, UTC+11) from the first Sunday in October to the first Sunday in April. Queensland stays on AEST all year.
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).
