The International Date Line
In preparing a Shiur two years ago, I gleaned many of these references from a Sefer whose name escapes me; it was something like "Mareh Mekomot beShe'eilat Kav HaTaarich...HaZeman." I think the author's name was Yoel Bloom/Blum. I would greatly appreciate the help of anyone who knows the name, so that I could properly credit the researcher.
