why is the local standard time?
Answers
Answer:
Local Time
Explanation:
The local time determined from a longitude passing through the middle of a country is regarded as the standard time.
Answer:
The key difference between Local Time and Standard Time lies in the fact that local time refers to the time which is estimated based on the sun’s movement, while standard time refers to the time which is fixed for particular places by the law of a country.
Local time changes depending on the longitude, whereas standard time is constant for a particular place.
While both the local time and standard time denotes the time of a specific place, there is a significant dissimilarity between the two terms.
Notably, the earth makes a full rotation, which is three hundred and sixty degrees, in twenty-four hours; hence, every time zone is fifteen degrees wide.
Time zones play a major role in bringing out the difference between local time and standard time. The following are the definitions and main differences between the local time and the standard time.
What is Local Time?
Local time refers to the specific time of a particular place expressed in relation to the longitudinal line that passes through the place.
The difference in local time of different places is due to the location of the places in different longitudinal lines.
Additionally, every place has the sun overhead at its own specific time, thus the difference in local time from one region to another.
For example, New York and Pittsburgh are two cities in the Eastern Time Zone with a different local time due to a six degrees longitudinal difference.

Local time is local to a city
What is Standard Time?
On the other hand, standard time refers to the time of the standard meridian of a particular country.
The difference in the standard time of different regions is due to the location of the places in different time zones of the world.
The standard time is reckoned by the distance, either east or west, from the Prime Greenwich Meridian of the longitudinal line within the subject region.
For example, despite being on different longitudinal positions, New York and Pittsburgh have a similar standard time.

Standard time is specific to the country. e.g. Indian Standard Time (IST)

Parameter of Comparison Local Time Standard Time
Meaning Time determined under the basis of the sun’s apparent movement. This refers to the fixed time of several places in a given region that fall under the same standard meridian.
Variations Changes with the change in longitudinal position. Changes with the change in time zones of regions.
Longitudinal Differences Places within the same longitude have the same local time. Places within the same longitude might have different standard time.
Computation of Time Time computed in reference to the longitude of the place. Time computed in reference to the time zone of the particular region.
Use Used to handle time-bound events such as transportation schedules. Used to get rid of the confusion that might occur when regions are in different time zones.
Main Differences Between Local Time and Standard Time
While taking a look at the local time and standard time of most places, there is a significant difference between them. However, that’s not the only difference between the two times.
The local time and standard time differ in several other factors, including their meaning, variations, longitudinal factors, measurement, and precision.
The following is a discussion of the main differences between local time and standard time.
Meaning
While both of the time refers to the time of a particular place, the local time and standard time remain different in terms of meaning.
The local time of a particular place refers to the time determined under the basis of the sun’s apparent movement.
On the other hand, the standard time refers to the fixed time of several places in a given region that fall under the same standard meridian.
