[SciPy-User] failing to create a scikit.timeseries object

With just datetime data, you probably want to create a DateArray.  I  
think that second resolution is the highest frequency available (at  
least that's what I see in the documentation).

Here's how to make a date array:

ts.date_array(freq='S', dlist=d)
DateArray([01-Jan-2010 10:10:02, 01-Jan-2010 10:10:02],
           freq='S')

I don't know if timeseries Date objects can resolve microsecond  
differences.
