MySql - SELECT TimeStamp Column in UTC format

In my Mysql 5.0 DB I have a column to control LastUpdated information. The Column is a TimeStamp one and MySql automatic updates data.

I'm trying to sel开发者_运维百科ect this column in UTC format.

The problem is that the server is setup to US datetime. According to MySql documentation, the DB stores the information in UTC but when I want to display information, it converts it to Server's time.

Is there any way to do SELECT command avoiding this convertion?

SELECT 
CONVERT_TZ(`timestamp_field`, @@session.time_zone, '+00:00') AS `utc_datetime` 
FROM `table_name`

I made a cheatsheet here: Should MySQL have its timezone set to UTC?

To avoid problems like the one mentioned by @spencer7593 with overlapping times, I recommend always storing dates in UTC

Besides changing the default timezone of the server, the timezone can also be adjusted per connection by executing this SQL statement:

SET time_zone = timezone;

Where timezone is the name of the timezone (see MySQL docs).

Alternatively, you can also convert a timestamp to a different timezone using the CONVERT_TZ function.

I needed to alter this to add the "Z" at the end of other things (i.e. like jQuery timeago) knew the time was UTC:

SELECT 
CONCAT(CONVERT_TZ(`timestamp_field`, @@session.time_zone, '+00:00'), 'Z') 
     AS `utc_datetime` 
FROM `table_name`
