EthGetBlockByHash The value returned is not correct

[Billyblingbling]

client := ethrpc.New("https://ropsten.infura.io")
hash := "0x931084475948fa771429ea3a5c39650e83a95059eff624d2089cc64c21e62915"
bl ,err :=client.EthGetBlockByHash(hash,true)
if err != nil{
log.Print("err", err)
}
fmt.Print("bl---",bl)
