I apologize you are unable to update your time zone as easily as you should! What browser are you working in? Are you receiving any error messages when you try to make this change in your settings? I have taken a look at your account and can see the timezone is currently saved to Hawaii. Are you unable to see this change? If so, I would suggest trying in a different browser or even a private/incognito window. Doing this allows us to see if there are any 3rd party add-ons that could affect how Constant Contact works.
