Hey!!! it looks like you are copy pasting stuffs from various forums out here... for fun???
I found the exact question that you had asked here:
Time Zone list in Excel[
^]
Answer to your question is also in that forum:
If the programmer is using PHP, they could use the standard names for the timezones, contained here:
http://www.php.net/manual/en/timezones.php
That's the list of all valid PHP timezones. You could simply copy those, put each name on it's own line, and give that to the developer in excel or text-file format. If you wanted more details, you could check out the source:
