select New and edit it to reflect the settings here then click OK and Close.
Now we have to do something a little trickier!
click on start and Run (or hold windows key + R)
Type in regedit and click ok (this will open the registry editor be careful here)
click on the +'s and expand/navigate out to the following place
HKEY_LOCAL_MACHINE/SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones\Norfolk Island
(this is put here by the The Tzedit you just did)

You will notice that the Std key above (it is not there) you have to make this!
First single right click on the blank area and "New >" pops up, mouse over and to the right and down select "string value".
A new string value appears, name it "Std" (capital S small td, "no quotes") enter. Std.
Then right click this and select modify, and put something like "Norfolk Island Standard Time" enter.

You should now have the Std key as above, this bit is finished, close it!
Remember you can right click and modify and delete if it is not right.

Now double click on the time on the task bar or right click it (as you would to set the time) and select change Time Zone from the options.
You will now find that Norfolk Island is on the drop down list of available places, feel free to select it and pat yourself on the back for a successful hacking job!
