When you reach a point where you have, say, half of your backup verification codes remaining and for some reason your timezone is that far out of sync that Google Authenticator no longer works (and for some reason you can't just sync your clock), then simply generated new backup verification codes and print those out. It seems like a pretty weird assumption that your clock will go out of sync and you won't be able to even manually sync. If you can get online to reach a Google login page, why can't you get within 30 seconds of the correct time for Google Authenticator to work?
