What year would your example choose?

The following works in 8.2.4:

select 'Wed Jul 11 2007 10:51:14 GMT+01:00'::timestamp with time zone
timestamptz
------------------------
2007-07-11 06:51:14-05

It appears to ignore the day of the week, though:

select 'Mon Jul 11 2007 10:51:14 GMT+01:00'::timestamp with time zone

timestamptz
------------------------
2007-07-11 06:51:14-05
