How to use the tzlocal.windows_tz function in tzlocal

def exchange_tz(self, exchange, exchanges=None):
        # NOTE(jkoelker) EODData's service is windows based, convert times here
        if exchanges is None:
            exchanges = self.exchanges()
        exchange_tz = exchanges[exchange]['time_zone']
        return pytz.timezone(windows_tz.tz_names[exchange_tz])

if WindowsZoneName is True, then it returns the name used by the Microsoft Windows Platform
    otherwise it returns the Olsen name (used by all other platforms)

    Note: this needs to get tested on Windows
