Title: Fix a.pypi.python.org

According to the PEP 381, this "a" is the master server.
I double checked it with "host a.pypi.python.org" and "host pypi.python.org".

Then I've found this interesting post by MvL with a script which checks "/daytime" to verify the clock of this master server.

I've ajusted the script accordingly. The delta should be 0s under normal conditions, if the master website is up.
