Alexandr Fedotov commented on IGNITE-4172:
------------------------------------------

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. LocalDateTime is stored as Timestamp, which should be accounted when applying a custom
SQL functions.

> 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.
