Americans turn their clocks back to winter (standard) time at 2 a.m. Sunday morning, returning to the seven-hour difference in the clocks between the East Coast and Israel. On the West Coast, the difference will be 10 hours. The time change in the U.S. previously took place at the end of October, but a new Congressional law mandated that summer (daylight) time be extended until the first Sunday in November.
The new law has caused havoc for many who depend on their computers for the right time. Most operating systems were not updated and jumped the gun, using the old date for the time change.
The time change in the spring in the U.S. will take place on the second Sunday in March, two weeks earlier than before the new law was passed. In Israel, the clocks will spring forward the last week of March and fall back the week before the Yom Kippur holiday.
