Since all this is about behaviour that is strictly internal to SQL Server,
the likelyhood that there is a interface, documented or undocumented,
to affect this behaviour is about nil. Who knows, maybe there is a trace
flag, but don't stay up all night looking for it.

If you are on SQL 2005, you could write a CLR function which retrieves
the system time from Windows, with the regular 100 ns precision.

If you are on SQL 2000, you would have to write an extended stored
procedure, which may not be performant enough. (There is quite a cost
for the eontext switch.)

But getdate() seems dead in the water when you are living in the fast lane
like you do.
