Time difference with major cities

| City | January | July |
|---|---|---|
| Los Angeles | 9:00 AM | 9:00 AM |
| London | 5:00 PM | 5:00 PM |
| Paris | 6:00 PM | 6:00 PM |
| Tokyo | 2:00 AM, next day | 1:00 AM, next day |

With Sydney, the gap is not the same in January and July: the clocks change at other times of the year there. With London and Paris, the gap is the same in January and July but one hour different for 21 days a year, because the clocks do not change on the same dates.
