I'm consistently getting about a 10% lower hashrate from Nicehash than multipool.us ... I thought it may have just been network related, but I just noticed most of my rejects say this -

I'm guessing that's what is killing my hashrate ... any known fixes for this? There's VERY little information online about rolling ntime period, and pretty much nothing about shares being rejected with this error ...
Antminer S2 running cgminer 4.3.5.
Now I'm producing invalid shares and being directed to the FAQ with that same miner ... did you change the way the pool handles invalid ntime? If so the FAQ could use an update because it doesn't address this specifically ...
