…ng data
Add the phoenix.query.applyTimeZoneDisplacement option, that causes the
java.sql time types to be treated as local times.
This option is disabled by default, it needs to be enabled to get the new
behaviour.

> We have two methods to write data when uses JDBC API.
> #1. Uses _the exceuteUpdate_ method to execute a string that is an upsert SQL.
> #2. Uses the _prepareStatement_ method to set some objects and execute.
> The _string_ data needs to convert to a new object by the schema information
> of tables. we'll use some date formatters to convert string data to object
> for Date/Time/Timestamp types when writes data and the formatters are used
> when reads data as well.

> *Uses default timezone test*
