I'm trying to parse an ISO date string in Python, but so far, I'm unable to make Python to apply the parsed timezone; it seems to apply the system on each and every time, unrelated to the parser library I'm trying to use.
What am I missing here?

The correct one should be 1438104476 for both, and that's not what happens.
