Storyboard: Leading Edge constraint correct, but Center X is off the screen

Question

I am so frustrated. Step by step directions for what I am doing:

I start with this in storyboard:

With a leading constraint:

And it shows up as expected in the simulator (ignore the different values):

Next, I try to change that constraint:

To a Center X constraint:

In storyboard it looks right:

But in the simulator it loads off the screen!

This is also true if I change it to a trailing edge constraint. I have tried the same thing on several widgets on this view. What could be causing this?

EDIT: To simplify the scenario I removed all other views except Current Time.

These are the only two constraints:

Again, it looks right on storyboard, but its messed up on the simulator.

EDIT: I think its also worth noting that I am using a view controller inside a container view.
