Seems to be a problem with checkpointing, It's updating faster than we can get a matching timestamp

I had the same checkpoint info.....
{
"synccheckpoint" : "0000000002bbfd2c9b920ea43eaa5bd5a4adcfeb11600ca96f650b53b1ad6f56",
"height" : 470708,
"timestamp" : "2014-07-02 02:06:21 UTC"
}
So it look that we are on the same page at least.....
