Abbreviation disambiguation
GMT is equivalent to UTC for everyday use. In the UK it also refers to the winter (non-daylight-saving) time; in summer the UK moves to BST (UTC+1).
On Clockjumper, AEST refers to Australian Eastern Standard Time, UTC+10 — the winter time in New South Wales, Victoria, Tasmania and the ACT. From the first Sunday in October to the first Sunday in April those states move to AEDT (UTC+11). Queensland stays on AEST all year and does not observe daylight saving.
