What would be different if the world had no timezones?

As an alternative to strictly adhering to a specific time zone, Hanke proposes that different locations should be able to adjust their working hours and schedules. However, business hours would vary between locations, even if the clocks are all set simultaneously. Since the local times would be determined by the sunrise or sunset locally, which would be based on the sun rather than time zones, you would be more connected to circadian rhythms, explains Hanke.

What is the advantage and disadvantage of the time zone?

TAI denoted Temps Atomique International, an essential component of Coordinated Universal Time (UTC), a time scale used to define local time globally. It specifies how fast our clock should run.

A continuous SI second is the basis for the international atomic time scale. At present, Tai is 37 seconds ahead of UTC, and Tai is also 19 seconds ahead of GPS.

On the other hand, Coordinated Universal Time represents the 24-hour standard used today as the basis for civil time.

Universal Time Coordinates is the standard time used globally. Coordinated Universal Time came into existence due to the close coordination between the world's time scales, hence the name.

What is the use of having time zones?

We must first understand the concept of time zones before understanding their purpose.

The expansion of transport and communication during the 19th century created a need for a unified timekeeping system, and time zones were introduced. Several instruments measured time before clocks were invented, including observing the Sun's meridian at noon. Historically, sundials and water clocks were the earliest timekeeping devices.

Purpose of having a time zones:

For legal, commercial, and social purposes, a time zone is an area on the globe that observes a standard time. Since areas in close contact need to keep the same time, they tend to follow the boundaries of countries and the subdivisions of those countries and not strictly follow longitude. A time zone observes a standard time for legal, commercial, and social purposes.

What is the purpose of having different time zones?

The world is divided into 24 slices of 15 degrees with multiple time zones, and the zones' clocks are set differently. The time is set the same for everyone in a given zone, and it differs by one hour in each zone.

How do you calculate longitude from local time to GMT?

Longitude specifies a place's position East or West on Earth's surface. Degrees of longitude are used to measure the distance between longitudes. 360 degrees make up a circle, and 360 degrees are in meridians. Minutes and seconds are separated by 360 degrees. Earth completes one rotation in 24 hours or covers 360 degrees of longitude in 24 hours. This means that the Earth covers 15° of longitudes every hour. One degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).

As the Earth turns from west to east, those places east of GMT are ahead of those that lie to the west of GMT. The Earth rotates 10 in four-minute.

Example: When it is 08:00 am in Mumbai, calculate the time at Wellington. Wellington is located at 1750E longitude, and Mumbai is located at 730E longitude. The difference in longitude between Mumbai and Wellington is 1750-730= 1020 (since both the places are in the eastern hemisphere, we will subtract one longitude from the other). The difference in time between the two places is 1020X4 minutes=408 minutes (we multiply it by four because one degree of each longitude takes 4 minutes to travel to the other longitude). Now 408 min= 6 hrs and 48 min. Since Wellington is east of Mumbai, its local time is ahead of Mumbai. We will add the difference, i.e. 6 hrs and 48 minutes, to the time in Mumbai. So, 8:00am+6 hrs and 48=14 hrs and 48 min= 2:48pm.

How can I determine my local time offset from UTC?

Let's take an example of Houston, Texas. That is United States Central Standard Time. To convery 18:00 UTC (6:00 p.m.) into your local time, minus 6 hours to get 12 noon CST. During summer daylight time, you can minus 5 hours. So here, 18:00 UTC would convert to 1:00 p.m. CDT (Central Daylight Time). With AM and PM, U.S. uses a 12 hour format.

Should we have one worldwide time zone?

It should not be possible because Earth is rotating, and it is not flat. This situation creates lights and darkness on the Earth. Because of timezones, we adjust our work time and make our daily activities active. Timezones make most things better and easier. Without timezones, daily activities would not be possible.
