Review Comment:
   Well two trackers running timers thread in parallel will trigger double of 
reads and then we have all duplicated infrastructure, with this approach we 
have much less code and little or no overhead when you don't have that time 
stamp.
   
   I think the new comments should make clear what this new time stamp is and 
if not please add some direction on what you think may be missing. Referring to 
commit 9bb0befe9a55c01bb3a5066a4b30137469819f38
