Beware: if it's a typical google feature then once changed it can never be changed back. They did this with login email settings and with reporting currency settings. I can't see any reason you wouldn't want the reporting in your local time but if you run into a reason, such as making charts align correctly for reports etc, you may be out of luck.
Can you confirm this by trying to change the timezone back temporarily netmeg? Is it possible?
