Fixes #243 Tuples should no longer be squashed in the event store

That is fine.  I just wanted to point this out that you could potentially filter out data where the timestamp is greater than the currentTimeMillis().  For instance in the EventExpirationFilter that extracts the timestamps from the Event specified timestamp may not correlate to a currentTimeMillis() but a time in the slightly in the future.  This filter would now filter out the data on a scan and throw it on the floor if a compaction occurs.

Also be aware that even with NTP, servers aren't perfectly synced to the millisecond all the time.
