How can I tell if my client is on the right fork?

getmininginfo
{
"blocks" : 1540,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 52.56812691,
"errors" : "",
"generate" : false,
"genproclimit" : -1,
"hashespersec" : 0,
"networkhashps" : 3037876280,
"pooledtx" : 0,
"testnet" : false
}
this is the right fork
/hope so/
