Yes, that's right, but I also tried to pass a DateTime() instance and got the following:

Python TimeStamp : DateTime.DateTime()
DateIndex value : 1073242822 
Metadata value : 2003/06/05 12:22:36.673 GMT+2

Is this DateTime index somehow useful (for searching?) in my catalog or should I throw 'em out ?
