Michi Mutsuzaki resolved ZOOKEEPER-1616. ---------------------------------------- Resolution: Duplicate This is fixed in ZOOKEEPER-1366. > time calculations should use a monotonic clock > ---------------------------------------------- > > Key: ZOOKEEPER-1616 > URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1616 > Project: ZooKeeper > Issue Type: Bug > Reporter: Todd Lipcon > > We recently had an issue with ZooKeeper sessions acting strangely due to a > bad NTP setup on a set of hosts. Looking at the code, ZK seems to use > System.currentTimeMillis to measure durations or intervals in many places. > This is bad since that time can move backwards or skip ahead by several > minutes. Instead, it should use System.nanoTime (or a wrapper such as Guava's > Stopwatch class) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
