Some Customers are seeing Calendar notifications one day prior to the actual date they are placed

Summary

In some cases, the notifications sent to watchers from a Confluence Calendar page is sending the notification for one day prior to the date it was actually in place.

Environment

Confluence 1000.1382.0

Team Calendar 1000.0.22

Expected behavior

Add an event for the 22/MAY/2017 and the watcher will receive the same date as it was placed on the Calendar.

Actual Result

The event added in the 22/MAY/2017 will show in the notification as been added on the 21/MAY/2017.

Workaround

None so far.
