Answer:
Local Mean Time (LMT) is a type of solar time, a timekeeping method using the Sun's movements across the sky. It is based on the average length of a solar day.In order to explain Local Mean Time, we first have to understand a few other terms:
Apparent Solar Time / True Solar Time
A sundial shows the true or apparent solar time. Because the Earth's rotation is not constant, solar days vary slightly in length. This means that the speed of true solar time is not constant.
- Mean Solar Time is based on the length of a mean or average solar day, which is 24 hours long. It moves at a constant speed.
- Local Mean Time is the Mean Solar Time for a specific location on Earth. It is the same for all locations that share the same longitude.
Answer:
Time zones are a relatively recent invention. They date back to the 19th Century and were designed to reconcile the needs of the then-new railroad industry with the ingrained habits of a population new to clocks.
They were a good idea at the time, but in the modern world they cause more trouble than they are worth. Now that several generations of humanity are accustomed to abstracting time away from the happenstance of where the sun is located, it's time to do away with this barbarous relic of the past. Everyone on the planet should operate according to a single time — Greenwich Mean Time would be suggested by tradition — and then local schedules could differ from place to place according to personal taste and local practicality.
