Some are more critical than others. 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.
