Dallas is 10 hours behind Karachi

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

Karachi and Dallas sit on opposite ends of the clock — a 10-hour gap leaves no common business hours to work with. Lean on recorded updates, shared docs, and clear handoffs so the 10-hour gap doesn't stall progress between meetings. Bear in mind Dallas shifts for daylight saving while Karachi stays fixed — recheck these hours after each clock change.
