Hi guys,

A couple hours ago I noticed on blockchain.info, we have an empty block chain accepted, follow the address for details
https://blockchain.info/block-height/288747

By empty I mean it contains no transactions except a reward for itself.
Moreover, as a later block in the main chain, it actually has a earlier timestamp than its predecessor.
I'm rather new to the bitcoin community, so I'm not sure whether this is normal or something is going wrong?
