NTP Servers
-
It seems like my pfSense instance is constantly checking the time on multiple servers, is this necessary? or is this something I can disable? and if I can disable it, how would I do that?
Thank you

Do you want time to be accurate? Out of the box pfsense uses ntp pool, which yes will be multiple servers that change even.. Yes ntp asks other ntp servers time and picks the best one to sync with.. And then yes checks quite often and then as its time gets in sync with the server it will back off on how often it checks, etc.. to longer between checks..
I suggest you research how ntp works ;)
But sure if you don't want it to use pool, you can set it to use specific ntp servers.. Public lists can be find on the ntp pool site.. But yeah normal ntp will talk to a few different ntp servers.. Unless your sure the one you talk to is correct and are not worried about it going offline, etc.
You do understand the amount of traffic 2 and from the ntp servers is very small right ;)
Look in status ntp, it will show you which peer your active with, which others are candidates, and which are outliers - it will also you show you how often will query them for their time.. should start at like every 64s and then slide upward to like 512/1024 seconds between queries..
If you just want to turn it off - remove all the listed ntp servers. No ntp servers listed, nobody to query.
