To change the time zone of the actual calendar, you need to do the following:

- open an internet browser that is NOT google chrome

- open the calendar you want to adjust

- scroll all the way to the bottom and click on "Options"
- click on "Time Offset"
- adjust the time eg Melbourne (14 hrs ahead of NY time)
- click "Change Time Zone"

Your calendar will then display in that offset time from New York time.

Here is a video also showing you how to do it.

NOTE: remember to adjust the offset if there is a change in time in your country eg daylight saving.

Check the offset ever few months to ensure it is still correct.
