TARGET() macro and default calendar (RuntimeError: option expired)

I am using the Python binding to Quantlib to perform calculations on historic data.

After setting up the required framework (curves etc), When I call `option.ImpliedVolatility()` I get the following exception thrown (for options that have expired):


      File "/usr/local/lib/python2.6/dist-packages/QuantLib/QuantLib.py", line 3683, in impliedVolatility
        def impliedVolatility(self, *args): return _QuantLib.VanillaOption_impliedVolatility(self, *args)
    RuntimeError: option expired


A snippet of the lines of code for setting up required curves etc is shown below:

            dividend_yield = YieldTermStructureHandle(FlatForward(0, TARGET(), div_yield, Actual365Fixed()))
            risk_free_rate = YieldTermStructureHandle(FlatForward(0, TARGET(), rf_rate, Actual365Fixed()))
            volatility = BlackVolTermStructureHandle(BlackConstantVol(0, TARGET(), annualized_histvol, Actual360()))


I **STRONGLY** suspect that the `TARGET()` macro used defaults to the current system date.

How may I set up the library to use a specific historic date?
