code: public static AccountingDate now(AccountingChronology chronology, ZoneId zone) {
          return now(chronology, Clock.system(zone));
      }
docs: Obtains the current {@code AccountingDate} from the system clock in the specified time-zone,
  translated with the given AccountingChronology.
  <p>
  This will query the {@link Clock#system(ZoneId) system clock} to obtain the current date.
  Specifying the time-zone avoids dependence on the default time-zone.
  <p>
  Using this method will prevent the ability to use an alternate clock for testing
  because the clock is hard-coded.

  @param zone  the zone ID to use, not null
