Australia has kept a version of the UTC atomic time scale since the 1990s, but Greenwich Mean Time (GMT) remained the formal basis for the standard times of all of the states until 2005.
Radio VNG also broadcast a spoken time signal every 15 minutes. The exact words in earlier years were: "This is VNG Lyndhurst, Victoria, Australia on 4.5, 7.5 or 12 MHz. VNG is a standard frequency and time signal service of the Australian Telecommunications Commission. This is VNG Lyndhurst, Victoria, Australia on 4.5, 7.5 or 12 MHz."

International Atomic Time (abbreviated TAI, from its French name temps atomique international [1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [2] TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3]
This scale allows for time comparisons between different clocks in the laboratory. These atomic time scales are generally referred to as TA(k) for laboratory k. [57] Coordinated Universal Time (UTC) is the result of comparing clocks in national laboratories around the world to International Atomic Time (TAI
A modern LF radio-controlled clock. A radio clock or radio-controlled clock (RCC), and often colloquially (and incorrectly [1]) referred to as an "atomic clock", is a type of quartz clock or watch that is automatically synchronized to a time code transmitted by a radio transmitter connected to a time standard such as an atomic clock.
The date and time in Australia are most commonly recorded using the day–month–year format (25 February 2025) and the 12-hour clock (2:49 pm), although 24-hour time is used in some cases. For example, some public transport operators such as V/Line [1] and Transport NSW [2] use 24-hour time, although others use 12-hour time instead.
