I'm using Mavericks,10.9.5.
The time on the menu bar exactly matches the time in the official Date and Time area… It is that time in the official area that is incorrect.
First the time was about 30-40 seconds fast, and then I had to restart the computer several times because of an unrelated issue, and now I'm nearly a minute SLOW. Using a comment that I found in another thread, I found the terminal (for the first time ever!), entered this:
sudo ntpdate -u time.apple.com
And the result was this:
31 May 15:29:14 ntpdate: step time server 220.127.116.11 offset 50.650629 sec
What is the next step in trying to fix this issue... preferably in words of one syllable?
