I'm told there is a C version of SLAlib but the person responsible is
reluctant to release it.  I believe Pavlos' PyAstro module has some
versions of these routines.

Considering the number of other scientific libraries out there, many of
these may already be available.

I'm working on a more generic TimeSeries class.  To populate this class,
I'm developing a wrapper class for Paul's PyFITS module that can extract
the time series data from FITS files generated for specific
instruments.  I think I can make this interface sufficiently general
that, in principle, one could design one to extract timing data for any
instrument.  It would facilitate multi-wavelenght timing analysis.

Also, I've heard no feedback from the AstroPy list on the PyFITS
documentation I wrote (come on, I know it's abysmal).  Suggestions
please!
