Description

Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Synchronizing internal VMM clocks provides uniformity of time stamps for VMMs with multiple system clocks and systems connected over a network.
