------------------------------------------------------------------
Apart from the improvements introduced by
[IGNITE-5483|https://issues.apache.org/jira/browse/IGNITE-5483] the following
should be addressed:
1. {{java.time.LocalTime}}, {{java.time.LocalDate}},
{{java.time.LocalDateTime}} are not supported as cache values or keys.
2. {{java.time.LocalTime}} is stored as {{java.sql.Time}},
{{java.time.LocalDate}} as {{java.sql.Date}}, {{LocalDateTime}} as
{{Timestamp}}.
Having, for example, {{IgniteCache<Long, Person>}} where {{Person}} has a
{{java.time.LocalDateTime}} field, trying to select that field with a query like
{code:sql}select locDateTime from Person{code}
will return {{java.sql.Timestamp}} value.

> We have is issue with querying LocalDateTime objects with our SQL engine.
> Next query can fails with error, if one of row localDateTimeField value has
> zero-time:
> select DATEDIFF('DAY', localDateTimeField, CURRENT_DATE ()) from t;
> Startpoint is IgniteH2Indexing.wrap() method.
> We need add support to these classes: LocalDate, LocalTime, LocalDateTime.
