You can install a real-time clock.  Unlike normal computers, the
Raspberry Pi does not have an RTC so when it powers up there is no way
to know the current time.   I don't understand the first warning, but I
have a RPI3 for weewx and I have a script to wait until NTP is happy
before starting the weather program (because it needs the date right to
interact with the weather station and log, long story not relevant).

If you choose not to install a clock, you should wait until NTP is
stable before doing anything that will cause trouble if the time is when
you last shut it down.

Note that DNSSEC and wrong time do not play well together, if you
machine is off for a long time.
