ICMP timestamp request and response packets have been standardized for nearly40 years, but have no modern practical application, having been superseded byNTP. However, ICMP timestamps are not deprecated, suggesting that while hostsmust support them, little attention is paid to their implementation and use. Inthis work, we perform active measurements and find 2.2 million hosts on theInternet responding to ICMP timestamp requests from over 42,500 uniqueautonomous systems. We develop a methodology to classify timestamp responses,and find 13 distinct classes of behavior. Not only do these behaviors enable anew fingerprinting vector, some behaviors leak important information about thehost e.g., OS, kernel version, and local timezone.
