[Tinyos-help] Bug in CC2420 timestamp

[Federico Fiorentin]

I'm working on time synchronization with tmote sky motes and TinyOS2.

I'm using a poller that sends a PollPacket every X milliseconds and a
set of clients that timestamp the arrival time of the PollPacket.
I found that the 16 timestamp in the time field of the Metadata are
somethimes incorrect ( CC2420Packet.getMetaData(msg)->time ).

This affects the 1% of the TimeStamps per mote.
I compared the value "timestamp(n) - timestamp(n-1)" of two different motes.

Is there any patch or a way to fix it?

I appreciate any advice
