CST is also used for China Standard Time (UTC+8) and Cuba Standard Time. Here CST means US Central Time (America/Chicago).

Eastern Time (EST / EDT)

Eastern Time follows the clock in New York. It is Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) from the second Sunday in March to the first Sunday in November.
