> By default, TajoClient uses GMT as client time zone unless session variable 
> {{TIMEZONE}} is specified. Also, by default Table uses GMT as table time zone 
> unless table property {{timezone}} is specified.
> This patch changes these default behavior as follows:
>  * TajoClient will use {{TimeZone.getDefault()}} by default.
>  * Table implicitly uses tajo.timezone by default.
>     * In other words, this default time zone does not affect the table 
> property in catalog.
> I also added the documentation about time zone.
