is all of australia on the same time zone
Time in Australia Australia uses three main time zones: Australian Western Standard Time (AWST; UTC+08:00), Australian Central Standard Time (ACST; UTC+09:30), and Australian Eastern Standard Time (AEST; UTC+10:00).[1] Time is regulated by the individual state governments,[2] some of which observe daylight saving time (DST). Australia's external territories observe different time zones.
Time in Germany The time zone in Germany is Central European Time (Mitteleuropäische Zeit, MEZ; UTC+01:00) and Central European Summer Time (Mitteleuropäische Sommerzeit, MESZ; UTC+02:00). Daylight saving time is observed from the last Sunday in March (02:00 CET) to the last Sunday in October (03:00 CEST). The doubled hour during the switch back to standard time is named 2A (02:00 to 03:00 CEST) and 2B (02:00 to 03:00 CET).
