Amazon Time Zone - AMT

Amazon Time or AMT has a UTC offset of - 4:00. This means that the time zone is 4 hours behind Coordinated Universal Time. The time zone is primarily observed by states in South America during the winter months when Daylight Saving is inactive. As soon as Daylight Saving starts – during the summer – some affected areas switch to Amazon Summer Time or AMST.
