    Description

      This is the grammar copied from SQL-2011:

      <datetime type> ::=
          DATE
        | TIME [ <left paren> <time precision> <right paren> ] [ <with or without time zone> ]
        | TIMESTAMP [ <left paren> <timestamp precision> <right paren> ]
              [ <with or without time zone> ]
      
      <with or without time zone> ::=
            WITH TIME ZONE
          | WITHOUT TIME ZONE
      
      <time precision> ::=
         <time fractional seconds precision>
      
      <timestamp precision> ::=
         <time fractional seconds precision>
      
      <time fractional seconds precision> ::=
         <unsigned integer>
      

      We extend this grammar to support "with local time zone" definition:

      time(0) with local time zone
      timestamp(0) with local time zone
