About the Buenos Aires-Cardiff gap
Buenos Aires sits in the America/Argentina/Buenos_Aires time zone (UTC−3), while Cardiff uses Europe/London (BST). That puts Cardiff 4 hours ahead of Buenos Aires right now.
These two cities do not handle daylight saving the same way, one adjusts its clocks seasonally and the other does not. The difference between them therefore moves by an hour twice a year, which is a common cause of missed meetings. The clocks above always show the live position rather than an assumed offset.
For scheduling, the practical overlap runs from 09:00 to 13:00 in Buenos Aires. Booking inside that band means neither party is dialling in before breakfast or after dinner.
