Some are more critical than others. If you're primarily worried about |
17 |
kerberos, variance of up to a couple minutes will likely go unnoticed. |
18 |
If you're dumping logs into splunk, and need second-precision timestamps |
19 |
to be comparable to each other across a multi-campus network, that's a |
20 |
different degree of time-sensitive. If you're using a distributed |
21 |
filesystem with time-sensitive conflict resolution algorithms, you could |
22 |
easily start caring down to sub-millisecond ranges. |
