Time in Australia is calculated using standard time, with three zones: Australian Western Standard Time (AWST), Australian Central Standard Time (ACST), and Australian Eastern Standard Time (AEST). The three zones use three standard UTC offsets: western (UTC+08:00), central (UTC+09:30) and eastern (UTC+10:00). Time is regulated by state governments, and within the three standard time zones daylight saving time (DST) differs between the states and the territories. Australia's external territories observe different time zones.

Standard time was introduced in the 1890s when all of the Dominions adopted it. Before the switch to standard times, each local city or town was free to determine its own local time, called local mean time. Now, Western Australia uses Western Standard Time; South Australia and the Northern Territory use Central Standard Time; and all of the other states and the Australian Capital Territory (A.C.T.) use Eastern Standard Time.

DST is used in South Australia, New South Wales, Victoria, Tasmania, and the A.C.T. It is not used in Western Australia, Queensland, or in the Northern Territory.

Gary Vaynerchuk (born November 14, 1975, in Babruysk, U.S.S.R. [presently Belarus]) is a video blogger, co-owner and director of operations of a wine retail store, and an author and public speaker on the subjects of social media, brand building and e-commerce. Vaynerchuk immigrated to the U.S. in 1978, and after graduating from Mount Ida College in Newton, MA, transformed his father's Springfield, NJ liquor store into a large scale retail wine store named Wine Library, and in 2006 started the video blog Wine Library TV, a daily internet webcast on the subject of wine, which launched his career of internet celebrity.

He has been featured in The Wall Street Journal,GQ, and Time, appeared on Late Night with Conan O'Brien and Ellen. Vaynerchuk has been described as "the first wine guru of the YouTube era", "the wine world's new superstar", and by Rob Newsom, a Washington State wine maker, "outside of Robert Parker, probably the most influential wine critic in the United States". In the July 2009 Decanter publication of "The Power List" ranking of the wine industry's individuals of influence, Vaynerchuk placed at number 40, citing that he "represents the power of blogging".
