Steps to Reproduce

Setup

1. Set up Liferay so e-mails to the admin user can be effectively received and seen.
2. Deploy Social Office, or at least the following plugins:
   • so-portlet
   • so-activities-hook
   • microblogs-portlet (dependency of so-activities-hook)
   • tasks-portlet (dependency of so-activities-hook)
3. Set a user's display settings to (UTC-5:00) Eastern Standard Time
4. Add the calendar portlet to a page.
5. Add the Activities portlet (the one from the "Collaboration" category, not the one from the "Social" category) to the page.

Reproduction

1. Create an all-day event on a site's calendar (likely "Liferay") in the future
2. View the event creation in an Activities portlet
3. Go to the arrow menu from the site's calendar:
   
4. Click in "RSS". Observe the event.
5. Click in the event. Click in "Edit".
6. Invite the admin user to the event. Save it.
7. Observe the invitation email.

Results

• At steps 2, 4 and 7 Event will show up as starting at 7PM the day prior to when you originally created the event. It should be starting at 12 AM.
