It's 4 seconds, then when you autoattack, the skill refreshes and goes to 6 seconds, then when you autoattack again the skill refreshes again and goes to 8 seconds. Theoretically you could have ghostblade's active on for almost 18 seconds if you autoattacked at the right times but it'd be very difficult and wasteful to do.
