Here's how to set your new time zone...
Actually, all advertisers will not see this option as of this moment. Rather, it is being gradually rolled out to everyone over the coming weeks.
While WebmasterWorld terms prevent me from being more specific, please be aware that there is an online resource where notices about such things as this are routinely published. Excerpting from April 27:
...Currently, all AdWords accounts are set to Pacific Time. However, in the coming weeks you’ll see a message in your account inviting you to set your account's local time zone. This means your entire account, including all ad serving, reporting, and billing, will be calculated and managed according to the time zone of your choice.It’s important to note that your account time zone can be set only once, so please choose wisely! Also, if you don't select a different time zone, your account will remain on Pacific Time.

Any timeline when this will be available to all? It will be a competitive disadvantage to those advertisers who are not able to use "ad scheduling" because they haven't yet had "time zone" rolled out.
Jim2003, although I am not able to comment on the exact timeframe (having learned in the past not to mention a hard date, as there is always the potential for it to change) I can say that 'ad scheduling' will not be released until all advertisers also have access to the option to change their date range.
I look forward to having it enabled in our account.
Always nice to see your name here Shak - I hope all is well. ;)
