Oops, I should have been more clear. You have this code: UUID timeUUID = getTimeUUID().randomUUID();
what you need is this code: UUID timeUUID = getTimeUUID(); What I meant by not understanding the error message was that I thought the TimeUUIDType gave a different error message than the one your're seeing when you put a random UUID into a time UUID CF. Try the above fix and see if it makes the problem go away.
