Assuming you're on a dialup, I'd stick it in ip-up.local. At least on a
RedHat system, the ip-up has a comment against modifying it. Presumably,
that's because when you update, it might get overwritten by the RPM. Thus,
any modification go in ip-up.local, and you don't lose them. But synching
everytime you dial up seems fine. I'm not familiar with this particular
method, but the ntp docs suggest against making large corrections - which
might be mostly related to how ntp functions, but seems good advice in any
case.
If I were on an always-there connection, I'd probably run it daily,
barring any other considerations.
