Invalid time because of daylight saving time not converted properly

[amuneric]

This time stamp

14MAR2010:02:00:00.000000

converted with this

  conversion:enhance [
     ov:csvCol          3;
     ov:csvHeader       "datetime";
     conversion:equivalent_property bpr:datetime;
     conversion:pattern   "ddMMMyyyy:HH:mm:ss.ssssss";
     conversion:comment "";
     conversion:range   xsd:dateTime;
  ];

converts as an untyped literal.

While this is a timestamp that shouldn't exist due to the jump to daylight savings, it seems reasonable to me that this get jumped (treat it as 14MAR2010:03:00:00.000000) and then typed.

5 million datetimes in my database, 101 datetimes untyped, 1/2 day scratching my head.
