Ok, further to my previous mails...

I have found that the year is reset to 2000 in my cmos clock on shutting  
down RiscBSD whenever I try to alter the clock. I.e. using date and rdate.

  The time is changed correctly, but on rebooting RiscOS, the year has 
been set to 2000 (time and day are correct).

  I have grabbed the latest version of rdate from NetBSD-current, but the 
problem persists.

  I can only assume that there is some problem with the routines that 
write to the CMOS clock in the kernel.

  Ale.
