Why We Have Time Zones

Posted by on Thursday, September 8, 2016

The concept of a worldwide system of time zones comes from Scottish-born Canadian Sir Sandford Fleming.

In 1879 Fleming proposed his system at several international conferences that led to the adoption of the present time meridians.

The local time is defined by the difference from Coordinated Universal Time (UTC), the world's time standard. The difference is expressed as either UTC- or UTC+ and the number of hours and minutes.

Several time zones are only 30 and 45 minutes apart. This makes the total number of time zones worldwide much higher than 24.
