Is it possible to access items using time instead of index via seekitem ?
But to use it you have to manually enable it

You mention the performance is a bit slow compared to c++ version. I wonder why you implemented this interface with pure python, rather than implementing it as an interface to c++ library?
I am using Debian 8 Jessie (stable) and Python 3.4 installed from the stable repos.
Here is what the installation looked like:

Cleaning up...When running this simple test program right out of the docs:
from teafiles import *
tf = TeaFile.create("acme.tea", "Time Price Volume", "qdq", "Acme at NYSE", {"decimals": 2, "url": "acme.com"})
tf.write(DateTime(2011, 3, 4, 9, 0), 45.11, 4500)
tf.write(DateTime(2011, 3, 4, 10, 0), 46.33, 1100)
tf.close()I get this result:
