Standard time refers to sun time, or time one would determine using a sundial.
I call it REAL TIME, but that is a Janice VanCleave term.
A time zone refers to a region of the Earth that has adopted the same standard time, usually called local time. Time zones were established in the in the U.S. and Canada by the railroads in 1883. But it wasn’t until March 19, 1918 that time zones were official established as a law in the U.S., sometimes called the Standard Time Act.This act also established daylight saving time. Daylight saving time was repealed in 1919, but standard time in time zones remained in law.
