Oslo is 6 hours behind Kuala Lumpur
Best overlap: 2:00 PM to 6:00 PM in Kuala Lumpur is 8:00 AM to 12:00 PM in Oslo.
Schedule calls for 2:00 PM to 6:00 PM in Kuala Lumpur — your colleagues in Oslo will be online from 8:00 AM to 12:00 PM. You share roughly 4 hours a day. That's enough for regular meetings, but treat the window as prime time and guard it. These times hold for most of the year, but Oslo's daylight saving (which Kuala Lumpur doesn't use) shifts them by an hour twice annually.
