So digging into the actual failure, this took a few tries as wrapping logging,
or flushing sstables seemed to make it hard to reproduce, I've confirmed it's
time based errors at least in this case:
row ts: 1583753957613001
dropped time: {{1583753957613000}}
{{[junit-timeout] Testcase:
testDropListAndAddListWithSameName(org.apache.cassandra.cql3.validation.operations.AlterTest):
FAILED }}
