Setting TimeZone for Plone Events

I'm pretty sure what I'm looking for can't be done out of the box by Plone (I'm running Plone 4), bu开发者_开发知识库t I want to specify the timezone of each event. Is there a pre-existing add-on to support this that anyone knows of, or will I just need to create a new content type based on the ATEvent type? I couldn't find anything with regards to this, other than someone requesting it be added to events back in Plone 2.

Any help would be greatly appreciated. I'm assuming I'll be creating a new content type soon but figured asking before hand couldn't hurt.

Thanks

The new event types in plone.app.event which is part of Plone since 5.0 do support timezones. You can have a look at the repo.
