Vancouver is 10 hours behind Nairobi

There is no standard 8-to-6 overlap. Someone joins early or late.

Nairobi and Vancouver live on different parts of the day. With 10 hours between them, standard working hours simply don't meet. Make the most of handoffs — end-of-day in one city becomes start-of-day in the other, so pass work along rather than meeting live. Note that Vancouver follows daylight saving while Nairobi stays put, so the times above drift by an hour seasonally.
