Seems like the only thing that might help there is changing to 24-hour format (which gets rid of the extra AM/PM that sometimes gets wrapped). Unfortunately that's not much of a solution to change a whole use case of something to essentially only hide an actual wrapping issue since it actually changes what is displayed--for example, 24-hour time isn't all that meaningful for many where it's not used.
