Dear all,

After posting my problem to TinyOs mailing list and searching a lot in 
TinyOs-help and following some hints, I still cannot find a solution to my 
problem which is described below:
 
I'm using tinyos-2.x and three micaz platforms equipped with MTS310 sensor 
board and once they receive a start sample command from BS, they will start 
sample the mic sensor immediately. Each mote timestamps the start and the end 
of the sampling process in order to compute the sample interval. My question is:

Why I always do receive different lengths of sample intervals (for example, 
with a STDEV of 601.1724757, 325.9728201 and 472.9102405 for the three motes)?

First I was using CounterMicro32C component and  Counter.get() command to 
timestamp the start and the end of the sampling process and then I tried to use 
CounterToLocalTime component as well. But in both cases I still have the same 
problem.

So, please share with me this problem and let me know your suggestions ASAP. 
Any hint might be useful for me and take me a step forward.

Thanks in advance,
Omar
