[Tinyos-help] LPL syncronization

as an aside... am I correct in thinking that
Radiotimestamping.transmittedSFD timestamps (or updates the timestamp field
for ) each successive LPL (re)transmission during the CC2420 "preamble"?

  async event void RadioTimeStamping.transmittedSFD(uint16_t time, message_t
*p_msg) {
    offset=time - (call PowerCycle.getLastWakeUp());
    call CC2420Transmit.modify( m_len -1 , (uint8_t * )&offset, 2 );
    t[6]=call Alarm.getNow();


p.s. I wonder how the official devel offering of a timestamping interface is
coming along...?
