the source value from jira is 10/Sep/20 where as in Confluence the rendered jira table shows as Sep 09, 2020, which is 1 day ahead of the original value.
The JIRA instance is running on Asia/Japan host where the confluence is running in UK host,
Could that be the reason?
When export xml for the original jira issue the date value is below:
<customfieldname>Target Release Date</customfieldname><customfieldvalues><customfieldvalue>Thu, 10 Sep 2020 00:00:00 +0900</customfieldvalue></customfieldvalues></customfield>
