 This problem -- dropping 2200 seconds of clock time -- is not seen in a
 FreeBSD 8.2-RC1 AMI on Amazon EC2 (ami-f77e4a83), using the same type of
 T1-micro VM as in the initial report.
 
 The clock drift noted with 9-CURRENT is also present in 8.2-RC1, but at
 about 40% of the rate, taking three hours and twenty-two minutes to lose
 an entire second.
 
 Best regards,
