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.
I am not sure why this is happening. Perhaps some more info would be useful. If you don't mind, click on Help --> debug window --> then click the open button under debug log file.
If there are any errors that show up there please report them here. This could be quite useful in figuring out the issue that you are having.
