Kernel is a straight compilation from source with no modifications to the GENERIC config file. >Description: Multiple system time calls such as gettimeofday show that system time is advancing at approximately double with wall clock rate. Output of test described below produces: Tue Mar 11 09:25:12 PST 2003 Tue Mar 11 09:25:22 PST 2003 Doubling the sleep value to 10 seconds produces: Tue Mar 11 09:27:08 PST 2003 Tue Mar 11 09:27:28 PST 2003 Verification of the sleep time to a wristwatch shows the sleep time to be approximately correct. >How-To-Repeat: Run the following from a command line shell such as /bin/sh: date; sleep 5; date >Fix: >Release-Note: >Audit-Trail: >Unformatted: K6/350 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
