Why is GetDate AND GETDATE() AT TIME ZONE 'GMT Standard Time' returning the wrong time?

Please see the code below: DECLARE @UKDateTime as DateTime SELECT @UKDateTime = GETDATE() AT TIME ZONE 'GMT Standard Time' print @UKDateTime PRINT GETDATE() This returns: Oct 4 2021 4:03PM Oct 4 2021 4:03PM The time in the UK is currently: 5:03pm (as confirmed by my PC clock). It appears to be returning the UTC date. What is the problem? I have SQL Server setup as a Docker container. It is SQL Server v18.4.
