    please add more test cases to test wrong dateformat, not exists columns, empty string

>
> Carbon support defining the Date/Time format. But the configuration for the same is present in carbon.properties and hence is global for all tables.
> This global configuration for timestamp format cannot support scenarios where different tables or different Timestamp columns in the same table.
> Suggest to provide option in the create table DDL itself to define the format for each Timestamp column. Also provide defaults so that users can create table with Timestamp columns without having to always define the Date/Time format.
