Hi Federico,
I met the same problem. I've written a time synchronization component
for TinyOS 2.x. Currently some (very few) synchronization messages are
discarded because of the error of metadata-time (earlier than
expected).
Hope some one can point out the reason.
Regards,
Min

As Miklos
I haven't done much work with the timestamps in the CC2420 apart from
Jonathan's original implementation, nor have I used it enough to have
experienced any type of erratic behavior. Is the issue here that the 16-bit
timestamp rolls over to 0 periodically? Would a 32-bit timestamp be better?
