I did wonder about that and hoped no one would query it!!! According to the NOAA Solar Calculator, the changeover on 15 April 1707 was about 19h GMT. He was born in Basel and I think they went over to the Gregorian Calendar in 1700/01. We were still Julian of course. Of course Basel is about half an hour ahead of Greenwich but this wouldn't shift the changeover date. I very much look forward to being corrected on several fronts by all the experts on this list!
