Kuala Lumpur is 13 hours ahead of Houston
There is no standard 8-to-6 overlap. Someone joins early or late.
Houston and Kuala Lumpur have no natural overlap. The 13-hour gap is simply too large for regular working hours to meet. Treat the handoff like a relay — Houston wraps up and leaves notes for Kuala Lumpur to pick up as their day begins. The difference isn't constant year-round: Houston adjusts for daylight saving while Kuala Lumpur holds steady.
