844/X does have the ability to output "burned in timecode" via the composite Analog Video output. I can't remember if you have to use Master to Tape to turn it on. It may just be a setting in the Prefs.
One thing to remember is that the Analog-out was intended for "reference" copies only. They put all their effort into making the SDI video look good, and didn't worry much about the composite analog out.
