description "
The wallclock device provides real time stamps, as opposed
to the eCos kernel timers which typically just count the
number of clock ticks since the hardware was powered up.
Depending on the target platform this device may involve
interacting with a suitable clock chip, or it may be
emulated by using the kernel timers."

the board power up."
