Some update:

With AVR Board 1.6.21

Code:

RTC.adjust(DateTime(year(), month(), day(), hour(), minute(), second()));

and

Code:

RTC.adjust(local);

both work, and give the same result, with AVR Board 1.6.22 only

Code:

RTC.adjust(local);

works! So, seems we have a fix that works on both versions, however I would like to know why the first instruction doesn't work with AVR Board 1.6.22. Something to investigate later.
