Countries in North America are very big though, and time zones can be shared between multiple countries (e.g. US and Canada). Just because we span a lot of timezones here, I wouldn't be confident to say, especially thanks to the eastern hemisphere, there isn't more countries than time zones. A timezone is a big, vertical slice that hits a lot of countries, I would have just as well believed there was enough overlap to have more countries than time zones.
