[SQL] selecting current UTC time

Hi,

Is it possible to select the current UTC time as type timestamp with time
zone?

select localtimestamp;

2008-09-14 21:55:24.367796

select localtimestamp at time zone 'UTC';

2008-09-15 09:55:42.3478+12
(not sure if what this result is)

select current_timestamp;

2008-09-14 21:55:57.844422+12

select current_timestamp at time zone 'UTC';

2008-09-14 09:56:07.661157
(is type timestamp without time zone)

I know this seems like a simple problem but I have searched the archives
and am unable to find a solution.

Any ideas?

Thanks.
