--------------------------------------
Summary: 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)
