A filter to remove samples that go back in time or are too futuristic.
Since the archived data has to go "forward" in time, going back is no option, and samples that are too far ahead of the host clock indicate a problem with either the IOC or host clock. If we stored such a sample, e.g. "1/1/2050", we could not add another sample to the archive until that date...
