TypeError: long() argument must be a string or a number, not 'datetime.datetime'

Hello,

I am having troubles getting started with minpower.

I followed the instructions on the website and successfully installed minpower/CPLEX. When trying to execute the sample UC case I receive the following output.

user@Computer C:\Users\user\minpower

You are using pip version 8.0.2, however version 8.1.0 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

I tested it also with a fresh install of Anaconda, but I receive the same output.

I am using numpy-1.10.4. If I downgrade to numpy 1.9.1 I receive the following error.

RuntimeError: module compiled against API version a but this version of numpy is 9 ``

I apologize. Obviously the error is due to an outdated pandas version. I am still stuck with this error, but I guess I can figure that out:
