> There seems to be a bug in {{TIMESTAMPADD}} function. For example, {{TIMESTAMPADD(MINUTE,
1, DATE '2016-06-15')}} throws a {{ClassCastException}} ( java.lang.Integer cannot be cast
to java.lang.Long). Actually, it tries to cast an integer date to a long timestamp in RexBuilder.java:1524
- {{return TimestampString.fromMillisSinceEpoch((Long) o)}}.
