| OCEANIA TIME ZONES |
Standard Time isin effect across most of the Oceania region.
During certain times Australia, New Zealand, Fiji, and Samoa switch to Daylight Saving Time.
Countries observing Daylight Saving Time will be marked with a (DST). Note: Micronesia is spread across two time zones, both +10 and +11 ahead of UTC.

The International Dateline is an important factor in determining the date and time of countries in this region.
Immediately to the left of the International Date Line, the date is always one day ahead of the date immediately to the right of the International Date Line. On the time and date codes shown below, note that Tonga 
and Samoa 
have the exact same time, but are actually one day apart, as Samoa is in the Western Hemisphere (to the east of the dateline) and Tonga is in the Eastern Hemisphere.
In summary, travel west across the International Date Line and you will gain a day, travel east across it and you will lose a day.

The worldwide standard for coordinated universal time, formerly known as GMT (Greenwich Mean Time), is now abbreviated as UTC (Coordinated Universal Time).
Some sources still refer to it as UTC/GMT and some web browsers, e.g. Mozilla Firefox, still display it as GMT.
The UTC Time (shown directly below) is the standard time zone upon which all other worldwide time zones are based. It never observes daylight saving time.
