Antonio,
What you need is Msp430CounterMicroC. It provides a 16-bit-wide counter with microsecond resolution. I'm not particularly familiar with the telosb, but there's a chance that the timer stops when the mote goes to sleep, so you might want to completely disable sleeping. Somebody more knowledgeable than I am could give you a more precise answer to this.

I'm implementing a Packet sniffer with the correspondent parser. I need a more precise timer to timestamp the packets when they arrive at Base(inter arrival time). A microsecond timer is more precise than the current one that I'm using. Basically I use the Timer.getNow() command which gives the number of clock ticks since the mote was turned on instead of a time. If there's a precise timer in Tinyos2 just tell me where I can find it. Thanks in advance.

You can have microsecond-precision counters, though. What platform are you using? What is it exactly that you want to achieve?

I needed it because I'd like to use the "struct timeval" to get time precision in micro seconds. If someone have already tried it, please attach me your code in the reply. Thanks in advance.
