How to get GMT (Greenwich Mean Time) rather than current time in earlier version of SQL Server ?

In SQL Server 2000 only a new function introduced to get GMT

But, What about the earlier version of SQL Server 2000/Before SQL Server 2000 ?

Before SQL Server 2000
DECLARE @GMTTimeZone INT
EXEC MASTER.dbo.xp_regread
'HKEY_LOCAL_MACHINE',
'SYSTEM\CurrentControlSet\Control\TimeZoneInformation',
'ActiveTimeBias',
@GMTTimeZone OUT

SELECT DATEADD(MINUTE,@GMTTimeZone, GETDATE()) [ANCIENT METHOD]
GO

SQL Server 2000 onwards
SELECT GETUTCDATE() [GETUTCDATE()]
GO

Note: This method applies to all SQL Server versions
