Because querying by date range is unreliable, and should be avoided wherever possible. The client's and the server's clock could be minutes apart and even if they were synchronized then multiple messages arriving in the same second can lead to difficult edge cases. I'd much rather query by the UUID injected into a message than by the approximate datestamp. Thijs
