+        <entry>an argIntervalType value of <classname>SQL_TSI_FRAC_SECOND</classname> or <classname>SQL_TSI_WEEK</classname> are not implemented since backend does not support it.
+        You may note that SQL_TSI_MONTH, SQL_TSI_QUARTER, SQL_TSI_YEAR are giving unexpected results since the backend assumes that there are 0 year in 900 days, 1 quarter in 900 days or 0 month in 92 days. </entry>
