Ottawa is 13 hours behind Kuala Lumpur
There is no standard 8-to-6 overlap. Someone joins early or late.
Practically speaking, Kuala Lumpur and Ottawa never share office hours; 13 hours of separation keeps their days apart. To talk live, someone has to flex: an early start in Ottawa can catch the tail end of the day in Kuala Lumpur, or the other way round. Bear in mind Ottawa shifts for daylight saving while Kuala Lumpur stays fixed — recheck these hours after each clock change.
