UTC+08:45 is used as atime in Australia (Central Western Time, or CWT). It is used by some roadhouses along theEyre Highway inWestern Australia andSouth Australia. Although not legally defined by the state or federal governments,[1] the boundaries where it commences and ends are clearly understood and recognised by theShire of Dundas local government[2] and are frequently shown on road maps of the area. Road signs at the western end of the time zone on the Eyre Highway advise travellers to reset their clocks by 45 minutes.[3]
The use of this timezone dates back to at least 1935. The April 1935Commonwealth Railways public timetable shows that 'Central Time' was used by that government organisation between Wynbring (in the East;Localities on the Trans-Australian Railway) andRawlinna (in the West). Passengers were advised to advance/retard their watches by 45 minutes each night on their journey.[4]

"If you go through Caiguna, [the sign] says move your clocks back 45 minutes. We say we're not that smart really so we just go with one hour, so we're one hour on from WA," he said.
