Kano, what does this mean? I'm still scratching my head over this one...same block number but different time stamp...

His miner submitted the block twice.
A 'duplicate' is accepted as a block since it's not impossible for the main pool node to see the block after it's main bitcoind sees it
(unlikely but not impossible)
CKDB spits out lotsa extra messages when this happens also - but I've coded it so that it just means one block properly in both situations
Edit: here's the main CKDB message related to it:
[2016-11-23 01:40:49.932+00] blocks_add(): Duplicate (1-Confirm) blocks ignored, Status: New, Block: 440140/...00001c50e5b79b5e/2016-11-23 01:40:49.930201+00
