Our version of percona-toolkit is affected by this bug https://bugs.launchpad.net/percona-toolkit/+bug/1078416 Which causes this check https://github.com/mozilla/identity-ops/blob/master/chef/cookbooks/persona-db/files/default/usr/local/nagios/libexec/check_mysql_percona_heartbeat to trigger false positives for an hour when the time changes. We'll need to fix this prior to March 9th 2014 http://www.percona.com/doc/percona-toolkit/2.1/pt-heartbeat.html
