at each place ,whenever the sun was directly overhead , it was considered noon this was called solar time.
Time based on the sun is called solar time. It is measured using the position of the sun in the sky.
Using solar time can lead to significant coordination issues, particularly in modern society where standardized timekeeping is essential for transportation, communication, and commerce. Solar time varies by location, meaning that different regions may operate on different times, complicating scheduling and travel. Additionally, the reliance on solar time can disrupt daily activities, as it doesn't account for variations like Daylight Saving Time or time zones, leading to confusion and inefficiencies.
A person cannot set the time on Casio Atomic Solar watch because it adjusts the time by itself. That is the feature of all atomic watches. They are radio-controlled therefore, no need to adjust. Besides, the watch is running on solar energy.
The apparent solar day is longer in January due to the tilt of the Earth's axis and its elliptical orbit around the Sun. During this time, the Earth moves more slowly in its orbit, which affects the Sun's position in the sky. As a result, the time from one solar noon to the next is slightly extended, leading to longer apparent solar days. This phenomenon is part of the equation of time, which accounts for variations in the solar day throughout the year.
To accurately determine the solar zenith angle for a specific location and time using calculations, you can use the formula: Solar Zenith Angle = 90° - (latitude + declination angle + time correction factor) where: Latitude is the geographic coordinate of the location Declination angle is the angle between the rays of the sun and the plane of the Earth's equator Time correction factor adjusts for the time of day and year By plugging in the values for latitude, declination angle, and time correction factor, you can calculate the solar zenith angle for the desired location and time.
the average of the mean solar time for a particular time zone
It very much depends on what is meant by solar time. Not really, it's fairly clear. There are 2 types of solar time: 1) "Apparent solar time". At any particular place this is called the "local apparent solar time", because it depends on longitude. 2) "Mean solar time". This averages out the natural variations of "apparent solar time". (The word "mean" is just a way of saying "average".) This too is depends on longitude of course, but time zones are used to cover a wide area, for convenience.
Because, when using "apparent solar time", the length of a "solar day" varies slightly during the year. (This is because the Earth's orbit isn't exactly circular and the Earth's axis is tilted.) "Clock time" is based on an average (or "mean") of these day lengths, called the "mean solar day". So clocks use "mean solar time". (By coincidence, on the date the question was answered (14th April) "apparent solar time" and 'clock' time are synchronised.) There's another reason for apparent solar time being different from clock time. "Clock time" uses time zones. So, over a wide area, the time on a clock equals the "mean solar time" at a particular, defining, longitude.
the distance between the solar time i.e Mean time apparent solar time is stated as equation of time. M.t-A.t=equation of time

Devisce used to keep track of solar time
Time based on the sun is called solar time. It is measured using the position of the sun in the sky.
The Earth "day" of exactly 24 hours is the "mean solar day""Mean" is basically a scientific way of saying "average". It's called a "solar day " because it's based on the position of the Sun in the sky.There are natural variations in the length of the solar day because of the Earth's elliptical orbit and axial tilt.The "mean solar day" averages out the variations that happen during the year.This makes things much more convenient for everyday life."Mean solar time" is based on the "mean solar day".The "apparent solar day" is the what we actually observe, and its length varies from day to day.A sundial measures "apparent solar time". We can convert this time to mean solar time by using something called "the equation of time".Actually, the sundial shows "local apparent solar time".That's because the time shown by a sundial depends on its exact longitude.For convenience, mean solar time has time zones (based on longitude).So, longitude also affects the relationship between these twomeasures of time.
Mean solar time on the prime meridian is known as Greenwich Mean Time (GMT).
