That does seem a bit excessive...
FWIW - It appears you're using an Asus router, correct? If so, you may want to consider running the AsusWRT Merlin firmware. In thelatest release (384.11) Merlin has added a local NTP time server. He also added the ability to trap and redirect all NTP traffic to the local NTP server. I just set this up this morning on my RT-AC86U router, as I would prefer my devices get their time from my local system. This would allow for my Hubitat hubs to boot properly and get their time sync'd, even if the internet is down for some reason.
