Expose calculated time zones from Recipient Time Zone feature in read-only format

Sending emails to recipients based on their time zone is a great new feature Marketo has delivered recently--and part of what makes it such a robust option is that it uses several fields and factors to calculate a recipient's time zone. That data would be incredibly useful if it was exposed to either the API or UI as a read-only field for calculating other actions on. Two that come to mind immediately would be smarter list segmentation and hooking into a technology integration (sending SMS messages at local times, rather than all at once.) Unfortunately, the system-calculated time zone is not available and thus users have to do their own time zone calculations today, making redundant work.
