The "Normalize Date" script also needs a list of indexes for the columns that contain dates. This can be acquired in one of two ways:
A string parameter on the PythonActor named 'indexes'
OR
A port named 'indexes' containing a StringToken.
In either case, the string must contain either a comma-separated list of column numbers or a formula describing a regular sequence that can be used to generate the list. The format of the formula is START + INCREMENT * COUNT. For example, the formula 7+4*10 means there are 10 columns in the list, dates occur every 4 columns starting with column 7. This would generate the list 7,11,15,19,23,27,31,35,39,43.
