How to show a clock at top of UITableView that constantly updates?
My users enter time information and I need to show local and UTC clocks (digital) at the top of the screen for them to reference.  How can I do this and have it update every second or few seconds?  I can add a header view or text to a section header/footer but I'm not sure how to refresh it.

Thank you.
