8072645: java.util.logging should use java.time to get more precise time stamps
Summary: j.u.logging uses j.t.Instant to store LogRecord time stamps. XMLFormatter format is updated to allow for a new optional <nanos> element containing a nano second adjustment. SimpleFormatter passes a ZonedDateTime object to String.format. LogRecord getMillis/setMillis are deprecated, replaced by getInstant/setInstant.

+ * this adjustment value will be printed in the new {@code <nanos>} element.
+ * The event instant can then be reconstructed using
+ * {@code Instant.ofEpochSecond(millis/1000L, (millis % 1000L) * 1000_000L + nanos)}
