Trinidad and Tobago is situated in the Atlantic Standard Time (AST) Zone. Countries or areas located in this zone keep Standard Time by subtracting four hours from the Coordinated Universal Time (UTC), thus UTC-4. Therefore, if the UTC is 6:00pm, in the AST region the time would be 2:00pm.
Some places in this zone follow Daylight Savings Time, during certain months they subtract only three hours from the UTC, UTC-3. However, Trinidad and Tobago does not recognise Daylight Savings Time.
