You might want to share the version of PostgreSQL you are using.You might want to try date_trunc and AT TIMEZONE function/operators-SELECT date_trunc('day', tasks_start at TIME ZONE 'EST')Note: I have not tried this statementIs this something you are going to use often? If that is the case then consider to re-model your query. The moment you use an _expression_ on a column it would not use a normal BTree index.
Hmm... I see....
select date_trunc('day', TIMESTAMP '2016-08-10') FROM tasks
And I get:
2016-08-10 00:00:00
Any idea?
