Every year there is a week-long difference between when the US changes over to daylight saving time, and when Europe does.  As a result, there is a week-long scheduling headache for international broadcasters who air programmes across both continents.  This year, CNBC's worldwide live daily broadcast, Worldwide Exchange becomes the focus for scheduling problems as a result of the changeover to Daylight Saving Time.

During the period of March 14th through March 25th, CNBC in the US will only air one hour (5AM-6AM ET) of Worldwide Exchange. In addition to the show regularly scheduled at 4AM ET on Fridays, Mad Money will re-air at 4AM ET on Sunday through Thursday.

The normal schedule resumes on Sunday, March 28th.
