Using time related smartvalues such as {{now}} result in an error "Failed to get value "

Issue Summary

When using smartvalues to retrieve time, we face the error "Failed to get value for now: {{now}}" when running the automation rule

Steps to Reproduce

Unable to reproduce so far what triggers the environment to reach this state.

When it is in this state, though, any rule with time smartvalues fail. For example, post a comment with {{now}}

Expected Results

The rule runs successfully.

Actual Results

We see in the rule log the message:

Error rendering smart-values when executing this rule:
Failed to get value for now: {{now}} 

Workaround

Set the timezone in the JVM arguments:

• Go to the setenv.sh file and add the parameter below:

  -Duser.timezone=America/Denver
  

  There is a list of available timezones here.
