Extract date from a TIMESTAMP(6) WITHOUT TIME ZONE NOT NULL column

[Patrick B <patrickbakerbr@xxxxxxxxx>]

Hi guys,

I'm using postgres 9.2 and got the following column:

start TIMESTAMP(6) WITHOUT TIME ZONE NOT NULL

SELECT start FROM test1;

2015-12-18 02:40:00

 I need to split that date into two columns on my select:

2015-12-18 = date column

02:40:00 = time column

How can I do that without modifying any column/data?

Maybe in a select?

Thanks!

Patrick
