While I'd agree 100% that SMPTE is not what's needed here,
your comments on its potential accuracy are misleading.

The *data* contained in the SMPTE timecode is quantised
to frames. But SMPTE is not just that data. It is data
encoded into an audio signal, and this can be resolved
to sub-microsecond accuracy.
