Checking for valid minimal date when getting transactions

[Wizady]

DKB only allows to get transactions up to three years in the past. If you want to get all your transactions and use e.g. 01.01.1970 as your date_from, setting the from and to fields does not work. The request will therefore return all transactions in the default timeframe (i.e. the last 30 days).

This unwanted effect could be mitigated by adding a feature to validate_dates that not only checks if the dates are not in the future, but also not more than three years in the past:

minimal_date_uts = int(time.mktime(datetime.date.today() - datetime.timedelta(days=3*365).timetuple()))
if date_from_uts < minimal_date_uts:
        date_from = datetime.utcfromtimestamp(minimal_date_uts).strftime('%d.%m.%Y')
if date_to_uts < minimal_date_uts:
        date_to = datetime.utcfromtimestamp(minimal_date_uts).strftime('%d.%m.%Y')

Good idea. Let me work on this...
