Ryan Svihla commented on CASSANDRA-15557:
-----------------------------------------
Yep makes sense. I'd feel better if I had some proof why it's happening now
(logging more or copying out the dropped columns table makes it not happen on
the boxes I've replicated it with), but either way it can definitely happen
with System.currentTimeMillis() and clock skew, and we'd need to protect
against that.
I reopened my PR and restored my branch with the client side timestamp, simple
