RTC bsp trouble.

[Leon Pollak]

Hello.
	I don't know what CPU and board do you use. The problem I saw with RTC in 
MPC860 was that RTC has 1 sec resolution, while RTEMS has theoretically 
unlimited resolution and is used also for system scheduling. I should say 
that TOD in RTEMS is more "buy product" rather then real target...:-))
