Time is requested over NTP every minute, overkill?

[ThinkPadNL]

I was sniffing with tcpdump on my network, when i found out that the GoodWeLogger is requesting time over NTP every minute.

Proof:

me@EdgeRouterX:~$ sudo tcpdump dst port 123 -i switch0.6                                                                                                 
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

I know these IoT devices (ESP8266) are prone to timedrift because they have no realtime clock (RTC) but every minute seems like a bit overkill to me. Shouldn't once per hour also be enough? For now i redirected the NTP-requests with a DNAT rule in my router (EdgerouterX) so that the router answers these queries (it offers NTP) instead of forwarding them to external NTP-servers.

P.S. The NTP-address isn't configurable right now from the Settings.h , maybe change that also when looking into this. It is now hardcoded in GoodWeLogger.ino line 24
