Time zones and time differences in Brazil

There are four different time zones in Brazil from West to East, which are usually traversed while on vacation. To that end, travelers should always synchronize their watches with the local time on arrival. Local time in Brazil is usually later than Central Standard Time (CST) that runs through the middle of the United States, referring to a difference of minus six hours in comparison to Coordinated Universal Time (UTC).
