Date data questionOn project chat right now is a question "For different date values with precision=9 (year), the value for month and day is variable. For instance, date of death (P570) for Yves Goldenberg (Q12743958) has the month and day as 0, while for Gheorghe Petrașcu (Q3595783) the month and day are 1...." 22:44, 25 April 2018 (UTC)) talk (TagishsimonI've been trying without success to see exactly what we store in the way of P570 for the two items. I'm guessing we should see a +1973-10-10T00:00:00Z/11 style date somewhere, and/or be able to get the precision value. Grateful if someone'd take pity on me, and provide a report that delves down & shows detail in this area. Starter for ten below. thx --
