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 statement
 
Is 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


I actually need just the date 2016-08-10, without 00:00:00...
Any idea?

Cheers
Patrick


I agree with @Tom, your first sql should work... Based on the table name "tasks" you provided, try this:


SELECT cast(jtasks_start as date) FROM "tasks" WHERE (date(tasks_start) in ('2016-08-11'))
