     <para>
      Valid input for these types consists of a time of day followed
      by an optional time zone. (See <xref
      linkend="datatype-datetime-time-table"/>
      and <xref linkend="datatype-timezone-table"/>.)  If a time zone is
      specified in the input for <type>time without time zone</type>,
      it is silently ignored. You can also specify a date but it will
      be ignored, except when you use a time zone name that involves a
      daylight-savings rule, such as
      <literal>America/New_York</literal>. In this case specifying the date
      is required in order to determine whether standard or daylight-savings
      time applies.  The appropriate time zone offset is recorded in the
      <type>time with time zone</type> value and is output as stored;
      it is not adjusted to the active time zone.
