You might want to try date_trunc and AT TIMEZONE function/operators- https://www.postgresql.org/docs/9.4/static/functions-datetime.html#FUNCTIONS-DATETIME-TRUNC SELECT date_trunc('day', tasks_start at TIME ZONE 'EST') Note: I have not tried this statement Is this something you are going to use often?
