Benedict Elliott Smith commented on CASSANDRA-15241:
----------------------------------------------------
Ok, I've [pushed|https://github.com/belliottsmith/cassandra/tree/15241-suggest]
some changes to report queueing time and running time separately. I've also
tweaked the naming of the methods from indicating _units_ to the _clock_ (i.e.
_approxTime_), but this is a weakly held conviction (I'm just unconvinced units
mean anything by themselves for a clock, since the epoch is equally important)
