TOPIC 1 TIME THEORY

The development of high-speed transportation and communications has reduced the relative size of the earth to the extent that people can now travel from North America to Europe in less than 3 hours; a message can be sent from any place on the earth and arrive at any other place in seconds; and weapons of every description can be deployed from subsurface, surface, air, and space platforms. As this technology was emerging, it became apparent that nations could no longer think in terms of local times and conditions. A standard time reference covering the entire world was needed. Without a standard time system, a routine airline flight plan for a Paris-to-San Francisco flight might read like this:

In computing the elapsed time for the flight, or for any part of it, individual calculations are necessary to adjust for time zone changes. There also might be changes for daylight saving time (DST) or other local differences. Time computations are easier if all times are computed on a common worldwide basis. Then, our flight plan is simplified, looking like this:

GREENWICH MEAN TIME (GMT)

To meet the need for standardization, the international GMT system was developed. All countries of the world adopted its use.
