macOS Cocoa Bindings pattern math

[davbeck]

is there any support for math in a binding display path? I would like to format NSTimeInterval as M:SS.

You can probably do what you want by letting the text field do the work. You just need to add a custom class of NSFormatter to the field.

Oh yeah I forgot about NSFormatter. I haven't used that since I first read Hillegass' book.
