timed question

[Andy Wai]

Could somebody tell me what the "-i" and "-n" flag on timed really does?
The man page doesn't tell me anything concrete and the "Timed Installation
and Operation Guide" isn't much better either.

Better yet, could somebody tell me what the proper command line is to
start a submaster daemon that will propagate the time to a small subnet
but won't try to take control of the backbone network should the master on
the backbone dies.

Thanks in advance.
