Seriously, clepsydra is one of the older ntp servers out there, and hasn't dealt with the leap second correctly. -----Original Message----- From: Kevin Day [mailto:toasty@dragondata.com] Sent: Wednesday, December 31, 2008 5:42 PM To: NANOG list Subject: Leap second tonight Just a reminder that there's a leap second tonight. Last time I watched for what happened on 01/01/2006, there was a little bit of chaos: http://markmail.org/message/cpoj3jw5onzhhjkr?q=%22kevin+day%22+leap+second+reminder+nanog&page=1&refer=cnkxb3iv7sls5axu I've been told that some of the causes of these problems are fixed on any reasonably recent ntp distribution, but just in case, you might wanna keep an eye out if you're seeing any weirdness. The worst damage I'd heard from anyone after that event was their clock being significantly off for several hours. -- Kevin
