[expert] silly question

[John Aldrich]

I used to know this command, but I haven't used it in awhile and it
now escapes me...
After I use RDATE to set the software clock, what's the command to
write the changes to the hardware clock? I know it's <something>
--systohc, but I"ve forgotten what it is.... can someone refresh my
memory?
        Thanks...
