Clock changes out of sync with the States
27th February 2007, 1:35 pm
The United States has changed the dates of spring and autumn Daylight Saving Time clock changes from this year. Over there clocks will go forward on the second Sunday in March and not the first Sunday in April as previously (Europe is last Sunday in March), with DST ending on the first Sunday in November, rather than the last Sunday in October.
This means, for instance, that between 11th and 25th March there will be a four hour, rather than a five hour, time difference between London and New York.
This could confuse direct communications, plus not all automated systems will have been updated. http://wwp.greenwichmeantime.com/time-zone/rules/usa.htm
