A story about the Rebbe Reb Shimon Sholom (R' Shimme'le) of Amshinov who spent Rosh Hashonoh 1940 in Vilna. He eventually escaped via Russia to Japan and Shanghai, China. Agav, the idea that he fasted two days on Y"K 1941 because he was in doubt - due to his crossing the International Dateline - is a myth. He was by that time already in mainland Shanghai. What he did about Shabbos is another story, which we'll leave for a later time.
