Roberto,

You are correct. Other than the inital jam of clock time, there is no
way in the 7 Series to use the TOD clock as the master reference. Drop
Frame would correct for the difference between TOD and timecode.

Sound Devices has posted a Sound Note about the differences between the
Timecode and TOD clocks here:
