You need to create something similar.
Suppose I decide to create this file for my native town (Yeisk, Russia). Though there is no stock exchange there yet, we can use this as an example.

So the first string in this file will be
Next lines show how the difference between the local and Greenwich time has been changed and will change in the future:
The first line 5,11,18,1883,2 means that November 18 1883 2hours am they started to use 5W difference between the local and Greenwich time.
This is format of this string
In the year 1918, on March 31, they started to use 4W time difference.
This string 4,3,31,1918,2 reflects this fact.
On March 3, 2006, at 2AM, the difference between Yeisk and Greenwich has been set on 3E (actually they mostly follow Moscow time there):
-3 means 3E.
after that on October 29, 2006 it became 4E:
So this is the content of the file Yeisk.tz
Save this file into a working directory and you click “Exchange Location” button. When you open it next time, you will find the new item there: Yeisk
