Do you know your Global Time Quadrants (GTQ)?
Time keepers use Coordinated Universal Time: UTC (also known as TUC or CUT) can get quite complicated. The professionals who are constantly updating their listings based on geopolitics, know how much detail is involved and how complicated it can get. To see, click on the embedded link within the word, Time keepers, just above (a Wikipedia window opens).
UTC is useful to keep the entire world on the same relative time with each other, but it is confusing to understand the most basic geography of time zones and how many countries within each geography share a common time.
Throughout this website and television series, every time zone will be known by the number of hours it is behind the beginning of the new day.
When the time turns 12:01 AM within any village on the International Date Line, Sydney should be 2 hours earlier or Time Zone (TZ) #3. Logically, it should be 9:01 PM in Seoul and Tokyo (TZ 4), 8:01 PM in Beijing (TZ 5), 12:01 PM in London (TZ13), 8:01 AM in NYC (TZ18), and 2:01 AM in Hawaii (TZ 23). Daylight Savings Time and countries that set their time on the half-hour make it difficult. Yet, once we know in which time zone a country or city is (and we know the time zone we are in), calculating the time within most other countries becomes easier. It is not an absolute number but it should be within three hours of their actual time. First, all of China is in one time zone (Beijing), then daylight savings, half-hour offsets, and geopolitical -- albeit local -- designations account for that three hour range and no less than 600 possible deviations from commonsense logic.
Obviously, this simplification of a complex subject needs refinement.
Notwithstanding, we really should eliminate all references to regional time zones. Consider in the USA, there is Eastern Standard Time (EST), Central Standard Time, Mountain Time, Pacific Standard Time, Alaska Time Zone, and the Hawaii-Aleutian Time Zone. Eliminate all those references to the region, and call Eastern Standard Time, Time Zone 18 (TZ #18). Automatically one begins to visualize every other country within the Time Zone (Canada, the Bahamas, Cuba, Haiti, Jamaica, Panama, Ecuador, Peru and a little part of Brazil). If known as TZ #18, one knows the time (within an hour because of daylight savings options) within those countries in that time zone and one can readily begin calculating the approximate time in the other countries around the world.
A different perspective. This is an introduction to a rather simple concept to use the 24 time zones to help orient our thinking about the world. It is an ordering system to learn geography and the approximate time (within a few hours) in most countries of the world.
The concept of the GTQ was first introduced in 2009. Those professional people who work to track and know the actual time in every location on earth have no use for the concept. It is too generalized.
However, if a person can visualize their GTQs, they begin to visualize the world in a new way. To do so, you need to be able to answer these key questions about the world's time zones:
1. What time zone are you in? Clue: Always between 1 and 24
2. What is the time zone 12 time zones away?
3. What time zone is 6 hours east of you?
4. What time zone is 6 hours west of you?
Although the Universal Time Coordinates (UTC) is used for determining time throughout the world, why not use the Time Zone numbers -- 1 to 24 -- to learn the relative relation of all the countries of the world and to determine the approximate time within each country?
Using a very simple logic, we begin with the area defined within 7.5 degrees east and west of the International Date Line and designate it, Time Zone #1. Then for every 15 degrees of longitude, add another hour right up to Time Zone #24. At any given time of the day, if you know the local time in your own time zone, you can more readily calculate the logical time in the other three quadrants. The net result is that you begin to visualize the entire earth's 24 time zones and all the countries in each.
*An exercise and demonstration
Now the first Small Business School office was in New Orleans (1994). In 2009, Small Business School opened a little studio there. That is within Time Zone #19 or TZ19.
Today's longitude and latitude lines were established as recently as 1884 when delegates from 25 nations, all using their own unique designations, convened the International Meridian Conference and formally adopted a system that used the Greenwich, England meridian as the Universal Prime Meridian. It established or instantiated the 0-points for longitude, and, of course, the equator established 0-points for latitude. The rest is just an extension based on elliptic geometries. These lines are just a convention that has been recognized and is used by every scientific person in the world.
