Incorrect descriptor result

[kostya05983]

Hello, @jmrozanec.
I use next cron expression 0 0 0 ? * 6 * and use class CronDescriptor.instanse(Msg.getCurrent()).describe()
I want to get at 00:00 at and Saturday day.
I get at 00:00 at and Friday days
I debug code and find that in DescriptionStrategyFactory, diff is always =-1, but if it is 0 result will be correct.

final Function<Integer, String> nominal = integer -> {
            int diff = definition instanceof DayOfWeekFieldDefinition ? DayOfWeek.MONDAY.getValue() - ((DayOfWeekFieldDefinition) definition).getMondayDoWValue().getMondayDoWValue() : 0;
            return DayOfWeek.of(integer + diff < 1 ? 7 : integer + diff).getDisplayName(TextStyle.FULL, bundle.getLocale());
        };

@jmrozanec I understand that it is happened because the week starts on sunday, how do you think, is it possible to provide functionality to start week on monday?

@kostya05983 please notice that we support Cron specifications to have a flexible start of week: you just need to specify which index corresponds to Monday at CronDefinitionBuilder: withMondayDoWValue(yourValueHere)
Please let us know if further explanations are needed. Best!
