I had a router that lost it's NTP servers and was off by about 20

what alarmed to cause us to notice and fix it.)


Trying to correlate logfiles with more than a several-second offset is
good and sufficient reason in itself to make sure everything is NTP-synched.

Of course, if your network runs so well that you never *notice* the offsets
because you never have to correlate logfiles, you're probably either a better
net admin than I, or merely more oblivious.. ;)
