The usual rc scripts do not wait for the daemon to be in sync.
What you may run into is the startup script trying to set the initial date
by way of ntpdate with an unresolvable ( per DNS ) or unreachable server hostname.

( On my SuSE Systems this timeout may eat upto 30 seconds of boot time. )

If you start/run your System in an "occasional user" manner
( i.e. switch it on, use for an hour, switch off ... ) you may well be better of
by just setting the time and leaving it at that. ( I have an old Win3.1 System
running that has gained 2 hours since i last adjusted its RTC 3/4 years ago.)
