How to use the databand.parameters.DateMinuteParameter function in databand

from dbnd import parameter

from dbnd_test_scenarios.test_common.task.factories import TTask

    dh = parameters.DateHourParameter()


class DateMinuteTask(TTask):
    dm = parameters.DateMinuteParameter()


class DateSecondTask(TTask):
    ds = parameters.DateSecondParameter()


class MonthTask(TTask):
    month = MonthParameter()


class YearTask(TTask):
    year = YearParameter()
