Description

While hll_hash_timestamptz wouldn't be terribly useful, hll_hash_date certainly could be. And it shouldn't be hard to implement; you can transform a date to an INT. However, since the range of INTs for a valid date would be different from 0-MAXINT, should we adjust the hash function somehow?
