Try to avoid doing anything that is time critical in task context. E.g. timestamping a message in ReceiveMsg.receive is inadequate, because it's called from a task. Similarly, Timer.fired is also signaled from a task, which has a non-negligible jitter if you want to use it for timesync. Doing as much as possible from within the interrupt handlers would solve much of your issues. However, syncing with the PC is still kind of problematic, since the time difference between sending out a message from your java app and receiving it on the mote has a pretty bad variance...
