If you're primarily worried about kerberos, variance of up to a couple minutes will likely go unnoticed. If you're dumping logs into splunk, and need second-precision timestamps to be comparable to each other across a multi-campus network, that's a different degree of time-sensitive. If you're using a distributed filesystem with time-sensitive conflict resolution algorithms, you could easily start caring down to sub-millisecond ranges. ------enig2QUSKGFQLEHSHKVFSDVNJ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJReWOAAAoJED5TcEBdxYwQ+uUIAICr34H4wmAgXj1+DLLsk5c0 7PR/7cMpre4LFrvAlnxO6SwhxwhNyp4xStFAqMVBSoxDU/+8Y9JmrSc95M/BYCSL GFQZP5sZOZaAoJRDAPis5yLijj3jUIZ3Uk1KKnJR3e5POpVVHh+0F06F1FwxqaM8 idSI59HUR3TzbeymApXFGepmpIJwNJf4+N0gJJ/thOtW4sPnwnIrjiqWz3beevlx Lg0VqlbKc4A39IJH7MbK5duHy4tfKOiFsrILMyAQL3q+HAiORNvzZQ2d7of8J8Kv eMvIp5Ei14a07WYW7g5rjDjogJNg7hYaMRkYcO5UxUGXXu9eZDvaGrQAuPDNwEo= =IY/+ -----END PGP SIGNATURE----- ------enig2QUSKGFQLEHSHKVFSDVNJ--
