Relatively accurate time measurement is required by the protocols I've

no, obviously it does not need to be absolutely accurate (they could
all synchronise to 3 weeks ago last tuesday) however there are few
sources of accurate clocks you can synchronise base stations too other
than GPS signals, which are highly accurate atomic clock signals
giving the correct time. So they all have the right time.

Why? For what purpose?

Why do I need to justify it?

because you're suggesting your experience would be relevant beyond
yourself, because of that, justification is kind of important.
