Keep meetings inside 8:00 AM to 1:00 PM in Athens — that maps to 1:00 PM to 6:00 PM in Kuala Lumpur. Kuala Lumpur is 5 hours ahead of Athens, which gives you a solid 5-hour window. Book earlier in it and neither side is rushing. Keep an eye on the calendar — Athens observes daylight saving and Kuala Lumpur doesn't, which nudges this window by an hour twice a year.
