Title: Warning: computer's date and time are incorrect!
Post by: Miner-TE on September 11, 2013, 12:04:29 AM
Anyone else seeing the following warning? I've checked the system clock and synchronized with NTP. System clock appears sane/valid.
My node is currently fully synced with the blockchain.

Are you using BitcoinQT?

How many connections do you have?

Bitcoin-QT V0.8.4-beta with 18 connection currently. Seems the problem went away after the restart just now.
Earlier, at lunch, I restarted the PC and went back to work. Didn't look too closely at Bitcoin-QT but I didn't see any warnings. Came home about 4 hrs later and the client was 2hrs behind in the blockchain and had the clock warning. I checked the clock and sync'd with NTP just to be sure but it was correct. The client at this time began catching up in the blockchain but still showed the warning message. Closed/restarted QT and the warning remained. I saw connections at this time.
Restarted the PC just after my post, then went to the store. Returned and started QT.... Warning gone and all is back to normal.
I must have become disconnected from the bitcoin network but I was still connected to the internet.

I got this too recently on my vps, after restarting bitcoind...
Restarting it another 2 or 3 times fixes it usually...
Not sure what is causing it, my vps is located in U.S. but I have
european timezone setup. Internal it probably uses UTC or unixseconds
anyway I think?

On Unix also check with command "date -u". This should ouput the "Universal Time Zone (UTC)", equal to "Greenwitch Mean Time (GMT)".
On Unix system the local clock should be set to UTC (or GMT), it's better for administration.

Can people please open up the debug console and run getpeerinfo when the error first happens and paste the results here?

My clock is correct. getinfo reports timeoffset at -7 initially, now at -3. Kind of another attack?
