Why only run ntpd during startup?

[DrRob]

Hi,

Why is ntpd only run to set the time during startup, rather than leave it running all the time?

I've just noticed that the Pi I set up at our church (to receive, process and upload recordings from a networked audio recorder) had the wrong time, I guess because there was a power cut, the pi booted and got a network connection to the first hop before the route to the Internet was up (there are five devices between it and the ISP).

If I altered the startup process to start ntpd without the -q option and then wait for the time to be set (year >= 2018), would that be a bad idea?

Rob.
