Last night we released AdWords local time zone support to all advertisers. Now you can set the time zone that you prefer for your account. Doing so will enable your ad serving, reporting, and billing to be calculated and managed according to the time zone of your choice.

Here are two important reminders. First, please keep in mind that you have until July 30^th to set your account time zone. If you don't select a different time zone, your account will remain on Pacific Time. Second, your account time zone can be set only once, so please choose wisely!
