[hibernate-dev] Timestamper

Hey, I wanted to draw your attention to "an issue" we've hit with the nonblocking implementation of Timestamper, that you guys use as well. Basically, if time goes backwards, calling next() would loop until time is passed the last seen value (see http://jira.terracotta.org/jira/browse/EHC-853) Technically, time shouldn't go back. Especially the DST issue is none in my opinion. But NTP daemons that do set clock back might be more common. As every session is timestamped, if I read SessionFactoryImpl.SessionBuilderImpl.openSession correctly, this would be larger issue to you guys now as well. There are obviously more people using Hibernate w/o Ehcache than with it. Anyways, as a solution to that, Chris and I came up with a non-blocking SlewClock implementation that would simply, in case System.currentTimeMillis() returns a value "in the past, slow time down until the wall clock has caught up: http://www.massapi.com/source/ehcache-2.4.3/src/net/sf/ehcache/util/SlewC... Since Timestamper is again core to 2nd level cache usage in Hibernate, it would make sense to this out of our code base and have it in yours (as well, as we'd still use it in for the 3.x). Should I go ahead and create a jira, pull request, ... ? Cause, based on my experience, blaming it on crappy env. hasn't really worked out for me ;-) Alex -- Alex Snaps <alex.snaps(a)gmail.com&gt; Senior Software Engineer - Terracotta http://twitter.com/alexsnaps http://www.linkedin.com/in/alexsnaps
