[SciPy-User] scikits.timeseries frequencies faster than seconds?

I've been using the timeseries objects for a project that analyzes wind data. A lot of the data I use has a frequency of about 10 minutes, and so the package works wonderfully. However, some of the data has a frequency of 20Hz and I would like to package it inside a timeseries for the sake of uniformity. Does anyone have experience creating timeseries with these "invalid" frequencies?
