Best Answer

There are four time zones in the contiguous United States; the Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST) and Pacific Standard Time (PST). Each time zone has a one hour difference between the time zones that it borders. The Eastern Standard Time (EST) zone borders the Central Standard Time (CST) zone on the east, therefore, 12:00PM CST would equal 1:00AM EST.
