Import strangeness

[DR]

I've set up an SQL request to import training-related data from an external (Oracle) database. The request works fine except that 5 records out of the 54 imported, display the wrong completion dates. In each case the month is correct, but the day and year are not.

I've also tried returning the dates as text with the same result. The same query entered through SQL_Plus returns all 54 records correctly.

Crazy.
