Clojure next.jdbc and SQLite datetime goodness
;; problem: date, time, datetime, and timestamp types in sqlite are basically just strings or numbers.
;; the sqlite jdbc driver doesn't coerce them into Timestamp, Date or Time types by default
;; but we want to use proper java.time types!
;;
;; solution: supply a builder-fn [0] that correctly returns java.sql.{Date,Time,Timestamp} types (and Boolean while were at it)
;;
