Hi, I'm not sure since which version I'm figuring this out, but before the same routers with same config didn't log so much that. It dirties up the log, cutting out many useful other infos.
Also, this is tagged as critical why? A change of 0,5 seconds respect the past isn't critical at all.
I'm logging on disk the critical errors and I want to exclude the NTP update from them, possible?

By the way, I consider that force a delay between updates (for exampel once every 4 hours for me is ok), or update only if the dirreence is more than X seconds, can imply solve all, possibile? Thanks

if this is doesn't matter for you - just exclude ntp in the desired (critical) topics

After version 7.13 it looks appeared a bug, the router keeping get time fom cloud and from NTP client (if configured), this creates a lot of time mismatches, disabling the cloud solved the problem.
Maybe a developer will read this and fix for the next versions, if an NTP is specified there are no needs to get time from cloud too
