title: How to have a app have open and closed times
body: <p>So far I am working on a app that has open and closed times, like if I wanted it to be open different times each day of the week. And the times that is would not be open it would have a error message that says "We are now closed". So far all I have found is <a href="https://developer.apple.com/library/ios/documentation/Cocoa/Conceptual/DatesAndTimes/Articles/dtTimeZones.html#//apple_ref/doc/uid/20000185-SW2" rel="nofollow">this</a> If you could help that would be great!!! </p>
