     [ https://issues.jboss.org/browse/WFLY-10584?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jörg Bäsner updated WFLY-10584:
-------------------------------
    Description: 
Given an hourly timer like this:

{code}
    @Schedule(hour = "*", persistent = false)
    public void hourlyTimer(Timer timer) {
        long methodEntryTime = System.currentTimeMillis();
        ZonedDateTime nextTimeout = ZonedDateTime.ofInstant(timer.getNextTimeout().toInstant(),
                ZoneId.systemDefault());
        logger.info("Call to hourly maintenance function completed in {} seconds, next timeout at {}",
                millis2secondsString(System.currentTimeMillis() - methodEntryTime), nextTimeout);
    }  
{code}

Results in the Timezone [Europe/Helsinki] on the 24th or March 2018 at 23:00:00 LocalTime in a next trigger of the same, see:
