Asof Join Exercise 11 - Session 2 - kdb+/q Developer (Level 1)

for Exercise 11 of Asof Join in Session 2 of kdb+/q Developer (Level 1), shall we use ``aj0` instead of `aj` to keep the real `pickup_time` in the actual record (jan09, the right-hand table) instead of the boundary time

Hey Xilin,

For this use-case, it looks like aj0 does make more sense. I will talk with the team about getting this updated. 

Thanks!
