standard time is the time of an area set by law. local time is implied based on the movement of the sun.
Explanation:
Standard time: in the us, there are 6 time zones; Hawaii-Aleutian time, Alaska time, Pacific time, Mountain time, Central time and Eastern time. There are 24 time zones in the world. Standard time is used more often because it is more specific and convenient.
Local time: places on the same longitude (the imaginary grid lines that cover Earth that go up and down) would have the same local time.
