+// Issue:        #cb459 - `gt` filter for submissionDate is not working as expected because of tz precision
+// Root cause:   Default timestamptz precision in postgres is microseconds and node/js has just milliseconds
+// Solution:     Let's change precision to milliseconds in database, since there is no value in having higher precision
+//               in the database when application can't use/handle it + typical usage of ODK Central doesn't demand higher
+//               precision.
