  1. record the data.
  2. read the data into MATLAB
  3. do a cross correlation between two channels and translate the lag to time

Have you looked at the documentation for xcorr?

Try two functions below:
GetTOFfftPhase
GetTOFcos(MySignal,RefSignal)
Those do exactly what you need with subsample resolution
