Summary
An automation for Jira rule that uses a date/time function might fail in a datacenter setup when there are multiple nodes and cluster nodes have different timezones.
Diagnosis
After enabling the debugging package com.codebarrel, an error will be logged to Jira-Home /log/atlassian-jira.log stating that a date/time function didn't work correctly. In the following example, now.plusBusinessDays(2) was not conclusive and didn't return a value.

stateChange=SOME_ERRORS, payload=MessageComponentChange{type=ERROR, key='com.codebarrel.automation.rule.mustache.error', appendParameters=[Failed to get value for now.plusBusinessDays(2): {{now.plusBusinessDays(2)}}]}}'}
Cause
One or multiple nodes of the cluster have a different timezone on the operating system level because of a misconfiguration or day light time saving change.
Solution
Make sure that all nodes report the same timezone
Go to Settings> System > System info, and ensure that all the timezone values match (System Time, User Timezone, jvm.system.timezone) across all nodes
Jira use the Operating System timezone by default, verify that all nodes are synchronized and display the same timezone
If it is not possible to change the operating system timezone, you can force it on the JVM level using a startup property and match the rest of the nodes
User timezone
