sql - How to get the date and time from timestamp in PostgreSQL select query?

How to get the date and time only up to minutes, not seconds, from timestamp in PostgreSQL. I need date as well as time.

For example:

2000-12-16 12:21:13-05 

From this I need

2000-12-16 12:21 (no seconds and milliseconds only date and time in hours and minutes)

From a timestamp with time zone field, say update_time, how do I get date as well as time like above using PostgreSQL select query.

Please help me.

To get the date from a timestamp (or timestamptz) a simple cast is fastest:

SELECT now()::date

You get the date according to your local time zone either way.

If you want text in a certain format, go with to_char() like @davek provided.

If you want to truncate (round down) the value of a timestamp to a unit of time, use date_trunc():

SELECT date_trunc('minute', now());
