RDS CT on Milwaukee FM radio

[ArgMeMatey]

I got a new car stereo for my old car.  It's a Kenwood and offers HD and analog reception of FM.  

However the "Time Sync" function has not "synced" yet to automatically set the clock.  Supposedly this looks at the RDS CT field and sets the clock based on what it sees there.  I can't find any specifics about whether any Milwaukee stations using RDS are filling the CT field.  Or, whether local HD Radio broadcasters are providing the digital equivalent.  

If you can shed some light on this, please post.  Thanks.
