It appears that the strftime function as applied to the timeseries Date class
gives incorrect results for the day of week c.f.
In [1]: import scikits.timeseries as ts
In [2]: from datetime import datetime
In [3]: ts.Date('D', datetime=datetime.now()).strftime('%a %d-%b-%Y')
Out[3]: 'Thu 26-Sep-2008'
