Hello,
.
Let's understand the standard Time in simple words where you can understand it clearly without using any extraordinary word's. Standard time is the time that is officially used by a country. It is a time that has been set up'ed by the law. Just like office timings of a company in a region, is the example for standard time. Let us assume Standard in means fixed, time in means the work, office timings of a company is a fixed work(standard time),at any cost a employee can't Change. So, the time which is apart from from law timings, which has not been set up'ed by the manually is known as standard time.
.
Officially, standard time is synchronization of clocks. Without using solar time and usage of geological to establish a local mean of time.

Standard time is also called as Local time in a country or a region during which synchronisation of clocks happens without any intervention of solar time. This is used when Day light saving is not in use. In other words, winter time is called Standard time. During Day light saving, the clocks are set one hour forward so that evenings have more light than the mornings. This is usually helps in increase of productivity in countries like US where Self employed are more. This means waking up earlier by an hour and utilising the sun light and reduce the usage of power. But during standard time, the clocks are brought back to normalcy and are synchronised with the local time of the country or region.
