[SciPy-User] scikits.timeseries: saving to binary file

[Tim Michelsen]

Hello,
according to the timeseries docs I can save timeseries objects to
a) text files
http://pytseries.sourceforge.net/core.timeseries.io.html#saving-a-timeseries-to-a-text-file
b) hdf5 using pytables
http://pytseries.sourceforge.net/core.timeseries.io.html#saving-a-timeseries-to-a-text-file

Why can I not store it as a numpy binary file using numpy.save without loosing
the dates and frequency information?

Thanks,
Timmie
