Only one date per TimeSeries ? Mmh, that's not really how it's supposed to work, but hey...
Try ts.concatenate
>>>  A=ts.time_series([1],start_date="2010-01",freq="M")
>>> B=ts.time_series([2],start_date="2009-12",freq="M")
>>> C=ts.time_series([3],start_date="2010-02",freq="M")
>>> ts.concatenate((A,B,C))
timeseries([2 1 3],
   dates = [Dec-2009 ... Feb-2010],
   freq  = M)
