Handling system clock changes in 64-bit apps

I've been searching around for answers to this with no luck...

When building for 32-bit, it was possible to get a notification when the system clock changed by using a Carbon UPP and the event kind kEventSystemTimeDateChanged.

But it appears that Apple took application event handling out of 64- bit Carbon, so this no longer works. How can I be notified, using Cocoa if at all possible, in a 64-bit app when the system clock changes? I've already tried listening for distributed & workspace notifications, and it looks like the only ones that get issued when the clock changes are implementation details only.
