Buenos Aires and Madrid
Buenos Aires runs on America/Argentina/Buenos_Aires and Madrid on Europe/Madrid. Madrid changes its clocks for daylight saving and Buenos Aires does not, so the difference between them shifts by an hour twice a year.
This is why the converter above asks for a date. A meeting arranged in October for a date in November can land an hour off if you assume today's difference still holds — the clocks move between the two moments, and only one side may move.
The safest habit for scheduling across zones is to agree on the local time in one place and let each side convert, rather than agreeing on "the difference". The difference is a property of a date, not of a pair of cities.
