Thanks for all the quick replies.

At this point, I think I'm just going to go ahead and use the
getExactTimestamp UDF. It's not a difficult to declare as I'd
remembered, and it will be good enough for what I'm doing. I don't
necessarily need it to be unique for the entire database, as long as
sequential operations from one workstation are each unique. For
example, if a client does an update, and then a delete, I just need to
know that the update happened before the delete, and ten thousandths
of a second should be small enough for that.

Thanks again!
