Thanks but I was more referring to reverse ordered timestamps for
composite keys to be used for sorting purposes.

HBase maps (row-key, column family name, column, timestamp) to a value.
The KeyValues are also sorted by the same attributes in reverse timestamp order.
The default timestamp is the current time, but you can set any long value
(which does not need correlate in any way to the time domain)
as the time stamp and hence define your own ordering within multiple version of
the same row key.
See Put: Put(byte[] row, long ts).
Is that what you meant?

Subject: Reverse timestamp
I understand the need but I don't understand how to generate a reverse
timestamp. Can someone please explain how this is accomplished and how I can
test that its working correctly?
Thanks
