   Yes and no.   
      
   To jet lag, per se, it makes no difference at all.  That's driven by the   
   difference in time zones between the two ends, not by the trip time.  If   
   you sat in your living room for the specified trip time, and were then   
   instantaneously teleported to the destination, you'd still have jet lag   
   when you tried to switch to the destination's sleep/wake schedule.   
      
   However, reducing the fatigue produced by the trip itself, and the   
   disruption of sleep schedules caused if the trip occurs during normal   
   sleep times, might make the transition a bit less unpleasant.
