Your Fairphone since -1 year 11 months 20 days

I have seen some discussions about this, that some people have a negative ownership of their device in the home screen widget. I just discovered this on mine as well, got it 5 days ago. This morning it was at -1 year 11 months 20 days, now (evening) it is at 21 days. I did not find a conclusion in the posts I found in the forum, maybe my search missed it.
I wonder what will happen in 11 days, when the counter will be at 31+1 days. Will it be at -2 years or at zero. Zero would be okay, a counter being just a couple of days off is okay. In that case, the device was shipped earlier than expected and I will surely not complain this early shipment.
How did the situation end up for the others?
