Issue Summary

This is reproducible on Data Center: (yes)

The due date shows one day behind in Confluence  as compared to Jira when the timezone is set to PST timezone in both Jira and confluence

There is a similar problem with a different root cause with the Target start / Target end custom fields, which you can follow here: JSWSERVER-21994

Steps to Reproduce

1. Start Jira and add the Due date field to the create issue screen
2. Make sure the system timezone is set to GMT +05:30 (Asia/Kolkatta) time zone for both Confluence and Jira
3. Create a Confluence page and add the new issues created on the respective page including value for the Due date. Here you will see that the Due date shows just fine on the Confluence side 
4. Now Change the OS time Zone to PST(i.e America/los angeles) 
5. Install Jira and Confluence on this server 
6. Repeat steps 1 and 3 and this time you will see that the Due date in Confluence shows one day behind 

Expected Results

The Due date should stay the same as it is reflected in Jira

Actual Results

The Due date shows one day behind in Confluence
