 Rather than searching for generic timestamp regexps, we could build a regexp based on expected values in the timestamp.

+[2020-12-19 Sat 05:55]  Seems to be working well.  Not sure how best to integrate with other timestamp-related predicates.  The code isn't that much, so maybe copying it into each predicate would be best.

+**** TODO Tests
+
+** PROJECT Multi-pass query normalization
+
+It would allow, e.g. one query to be normalized into another, and then into another.  It would be helpful for timestamp-related ones, I think.

 ** PROJECT [#B] Optimization for ~olp~ predicate
 
 I noticed that, of course, a search like =h:bar olp:foo= is much faster than =olp:foo,bar=.  Then I realized that the last argument to =olp= could be removed and replaced with a =heading= predicate with that argument, which is much faster.
