Subject Re: [leap second] Anyone else experiencing high rates of linux server crashes today? - Server Fault
Date Tue, 03 Jul 2012 15:42:01 GMT

I won't go in to that here, but to fix, you have to turn off ntpd and then run the previous
mentioned date commands to set the time then start ntpd back up.
