Standard time zones are 15° wide because Earth rotates through that distance in one hour. This allows for uniform timekeeping across the globe. While the initial establishment of time zones was primarily done by developed countries, today they are used worldwide. In North America, time zones are spaced at 15° intervals of longitude.
