Oh no, it's a real thing. A lot of POS coins have tight timedrift specifications. Meaning if your PC's clock is off by just a few seconds, your blocks will get rejected. I included a picture below. Just click on that 'update now' button to resync the clock on your PC. 95% of the time people say they are getting a lot of rejected blocks in any POS coin, this is the reason. I do it frequently on the PC that I stake coins 24/7 on. Your PC probably just automatically resynced it's clock so now you are fine, but just an FYI in case it happens again.
lol ok thanks
my pc was on time.windows.com i changed for time.nist.gov
now i'm to 4 accepted in a row
thanks
So suddenly yesterday this happened to me too. I've tried re-sycning to time.nist.gov; for a while it was showing 23h or 25h behind; now it's back to just saying "out of sync." Any additional ideas? I've left it running for several hours each time, I'm also showing minimum 8 connections to the network. It's also odd that it says its staking, but again it remains in this "out of sync" state. Last successful stake was the morning of 8/2/15.
