On Motzei Shabbos, Israel will move from daylight savings time to standard time at 2:00am, moving clocks one hour back. This is the annual practice, on the eve of Yom Kippur, to permit ending the fast at an earlier hour of the day.
Daylight savings time begins on the last Friday prior to April 2nd and ends on the last Sunday before 10 Tishrei, Yom Kippur.
There will then be a six hour difference between Jerusalem and Eastern Standard Time.
