The time difference between Turkey and the U.S. time zones will increase by one hour beginning Sunday.

Daylight Saving Time ends Sunday in the U.S. at 2 a.m. local time (0600GMT), as Americans turn their clocks back one hour. It will add an additional hour to the time difference between Turkey and the U.S. after Ankara recently announced changes to its time keeping.

Turkey said in September it would continue observing Daylight Saving Time throughout the year.

When Americans turn back their clocks Sunday morning, the time difference between Turkey and the U.S.'s Eastern time zone will be eight hours, instead of seven-- in cities such as New York, Washington DC, Atlanta and Miami.

In the Central time zone, in cities such as Chicago, Dallas and New Orleans, the difference will be nine hours, instead of eight.

For cities like Albuquerque, New Mexico; Denver and Salt Lake City, instead of the usual nine-hour difference with Turkey, it will be 10 hours.

For cities in the Pacific time zone -- Las Vegas, Los Angeles, San Francisco and Seattle – the usual 10 hours in difference now extends to 11.

And the difference between Alaska and Turkey will increase to 12 hours from 11, while Hawaii goes from 13 to 14 hours.

The new time differences will be in effect until March 12 when the U.S. once again would begin observing Daylight Saving Time.
