Subject: Why all raid devices do have zero 'time in queue' value?

Good day.
I've look to stat for all MD devices I have (raid0, raid1, raid10) - all
of them reports 0 for time_in_queue field in /sys/block/mdX/stat file.
Is any reason why all raid devices contains no information about time
spent on requests processing?
Thanks.
