Convert a date and local time
All dates are local to the named city. If a time occurs twice when clocks go back, the earlier occurrence is used and a warning appears. Skipped times are flagged.
Daylight saving and the time difference
Both cities change their clocks, but on different schedules. The UK switches on the last Sunday in March and October. New York follows the US schedule: the second Sunday in March and first Sunday in November. Use a specific date for calls during those weeks.
