Key: JBCLUSTER-213
URL: https://jira.jboss.org/jira/browse/JBCLUSTER-213
Project: JBoss Clustering
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Reporter: Radoslav Husar
Assignee: Brian Stansberry
Priority: Minor
When new node joins the cluster, It can simply exchange time with other nodes. If the time
is off by significant number of seconds, it would warn the administrator to synchronize
the time on cluster machines. Since some services depend on having time synchronized, this
could help users to find this problem quickly.

Brian Stansberry resolved JBAS-6092.
------------------------------------
Resolution: Done
This is done via the TimestampDiscrepancyWarnService configured in
deploy/cluster/timestamps-jboss-beans.xml. By default it logs a WARN if it detects a
discrepancy of > 2 minutes in the system clock of the node and another node. It can be
configured to log an ERROR instead, and the max discrepancy can be configured as well,
with ms precision.
TimestampDiscrepancyWarnService uses the general purpose TimestampDiscrepancyService as
its source of data on system clock differences. That service uses a group RPC over
HAPartition to check for system clock differences. The accuracy of the check is only as
good as the amount of time it takes to make the group RPC. So, this service should not be
configured to warn about very small differences.
