Date/time (inst-time.ss): java.util.Date / java.sql.Timestamp ctors accept ms or
another date value (ms-of) -> a jinst; java.text.SimpleDateFormat (pattern + .format
via the existing format-ms UTC engine; .setTimeZone accepted); java.util.TimeZone/
getTimeZone. instance? answers Date true / Timestamp false for a jinst (a Date is
not a Timestamp on the JVM).
clojure.edn/read over a reader (io.ss + post-prelude): the overlay edn.clj's
drain-reader is janet/type-coupled, so Chez drains the jhost StringReader/
PushbackReader to a string and reads the first EDN form. Unblocks jolt-uicd.
Native Chez throughout (no vendoring): Chez date arithmetic + string ports. zero-Janet
2688->2692, 0 new divergences; self-host + Janet gate + JVM cert green.
