About the Cardiff-Phnom Penh gap
Cardiff sits in the Europe/London time zone (BST), while Phnom Penh uses Asia/Phnom_Penh (UTC+7). That puts Phnom Penh 6 hours ahead of Cardiff 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 11:00 in Cardiff. Booking inside that band means neither party is dialling in before breakfast or after dinner.
