The boundaries of time zones correspond<span> roughly to lines of longitude
</span>This is why:
<span>The time in each successive time zone is one hour different from the times in neighboring time zones. To establish time zones,
Earth's rotation rate of 360 degrees of longitude per day was divided
by 24 hours. The result shows that Earth turns 15 degrees of longitude
per hour.
