From 157ece6ced7b093701bd10f3a3cd42c5559529a0 Mon Sep 17 00:00:00 2001 From: Jim Hahn Date: Tue, 3 Mar 2020 11:55:02 -0500 Subject: Add gson adapters for special field types Added type adapters for Instant, LocalDateTime, and ZonedDateTime. UUID seems to work already. Added new Coder that offers an alternative encoding for Instant.
