+1 on this.

I think you should generally not blindly apply the MATLAB approach. 
Python is a more powerful language than MATLAB, and support for more 
than just doubles is one it's features!

How does the datetime module store the values in a datetime object? My 
first inclination would be to follow it's approach, but it may not be 
suited to arrays ( :-( )

A couple projects you might want to make use of:
