> There is an issue when you call getTimestamp() on any KV handed into a Coprocessor's
prePut(). It initializes the internal "timestampCache" variable. 
> When you then pass it to the normal processing, the region server sets the time to the
server time in case you have left it unset from the client side (updateLatestStamp() call).

> The TimeRangeTracker then calls getTimestamp() later on to see if it has to include the
KV, but instead of getting the proper time it sees the cached timestamp from the prePut()
