Hello,
Are you using the TestFtsp folder and the FtspDataLogger? In my experience,
that only happens if node 2, 3, and 4 cannot hear node 1 (maybe too far away,
or blocked, or no FTSP code running) so there is two global times: one for
nodes 2,3 and 4 and another for node 1.

Hello all, it's first time here.
I am playing with the TestFtsp application on TinyOS 2.1.1 using MicaZ and the
32KHz timer precision, having an average error of around 100 microseconds in my
experiments (3-4 clock ticks).
I have learned that FTSP can have precision in the microsecond range, so I
n FTSP and it claims that it has an average time
sync error within microsecond. Can I know if there is any modifications that
I must do to reach that microsecond error? Can I add an external clock to
increase the resolution? Or am I just currently doing something wrong?
Thanks for the help.

er? I imagine having motes that
have blinking LEDs at the same time (not that precise) while booting at
different times. What command and interface can I use to overwrite the
current time of a timer? Thanks for your help.

I am currently disregarding the clock drift and jitter. Do you have any
suggestions on how to use the computed offset in order to have a timer
firing at the same time? Can I use the startPeriodicAt(t0,dt) command?
Thanks for the help.
