Time synchronization in logging ensures that events from multiple machines can be ordered and correlated. When clocks run at different rates or aren’t aligned, a log from one system might appear before or after another even if the real sequence was different, making it hard to reconstruct what happened or attribute actions correctly. Relying on each system’s local clock without coordination leads to drift that accumulates over time and disrupts cross-system analysis. Manual time updates are error-prone and slow, so they’re not reliable for ongoing operations. Using a time protocol like NTP ties all systems to a common reference, automatically adjusting for drift and network delays, so timestamps across the whole environment line up. This provides a consistent timeline for troubleshooting, security investigations, and audits, enabling accurate event correlation and reliable forensic analysis.
