According to Rav Tikochinsky.... The Live of Rav Yechiel Michel Tikochinsky

One of the leaders and influential poskim of the Old Yishuv in Jerusalem, Rav Yechiel Michel Tikochinsky (1871-1955) had an outsized impact on the world of halacha, especially in regards to zmanim- halachic time. As the long-time administrator of the Eitz Chaim Yeshiva and accompanying institutions, he oversaw its move to the new city in Yerushalayim, where it entered an era of expansion and growth. He pioneered many areas of halacha, including the laws of mourning, shmittah, the halachic international dateline, laws of Jerusalem and the Bais Hamikdash. Having cultivated both a love as well as a keen understanding of astronomy from a young age, he arrived at formulas for calculating the various zmanim in halacha. In 1905 he initiated the publication of what was to became an incredibly influential calendar where he presented his views on zmanim and customs of Jewish life.
