JST
The common time zone in Japan is the JST (Japan Standard Time). It is 9 hours ahead of Coordinated Universal Time (UTC+9). In Japan, Daylight Saving Time is not practiced, and thus JST does not change throughout the year. For the right time zone, check the JST Time Now.
ACST
In central Australia, 9.5 hours ahead of Coordinated Universal Time (UTC+9:30) is used (ACST). South Australia and Broken Hill use the Australian Central Daylight Time (ACDT, UTC+10:30) instead of the Northern Territory year-round, during the summer, to obtain more evening light hours.
