> issue/request:
> sstablemetadata should show tombstone timestamp not just the local drop time
>
> I'm not sure what all versions this exists in but the sstablemetadata
> tombstone "drop time" only just shows the local delete time of the
> tombstones. What's more important (what the tombstone expiration time
> depends on) is the tombstone writetime (tombstone timestamp). It's possible
> to, and a surprising number of users have done this, write a tombstone with a
> timetamp in the future (by doing "DELETE...USING TIMESTAMP
> <future_timestamp>"). When this happens, the tombstone hangs around in
> sstables for a lot longer than users expect because
> {code:java}
> tombstone_expiration_time = gc_grace_seconds + tombstone_timestamp{code}
> NOT
> {code:java}
> tombstone_expiration_time = gc_grace_seconds +
> tombstone_local_delete_time{code}
> and the sstablemetadata output doesn't help here because it only shows the
> local delete time, not the actual tombstone timestamp that's used to
> calculate tombstone expiration time.
