I have a simple select query such as below but I noticed I am getting back the regional times. How can I convert to UTC in my select statment?

select myTimeStamp, MyName, MyBranch from tableA

Result: '27/03/2014 15:15:26' 'john', 'london'

I have tried using sys_extract_utc (myTimeStamp) but I have the error

sql command not properly ended

The column myTimestamp is of type 'date'.

select cast(mytimestamp as timestamp) at time zone 'UTC', 
       MyName, 
       MyBranch 
from tableA

Because mytimestamp is in fact a date not a timestamp you need to cast it. Doing that makes Oracle assume that the information stored in mytimestamp is in the time zone of the server -if that isn't the case you need to use Madhawas' solution.
