What is the importance of timestamps in an event log?

Timestamps are critical in an event log because they indicate when specific events occur within a process. This temporal information is essential for analyzing the sequence and timing of events, which helps in understanding the flow of the process and identifying bottlenecks, delays, or inefficiencies. By tracking timestamps, practitioners can perform time-based analysis that leads to insights into process performance, helping organizations improve processes based on empirical data.

For example, if a business process is experiencing delays, timestamps allow analysts to pinpoint the exact stage at which these delays occur. Analyzing this data helps organizations make informed decisions on where to focus their process improvement efforts.

Other options, such as the portrayal of timestamps as purely entertaining or dismissing them entirely as functional, overlook their vital role in process analysis and operational efficiency. Also, while security can be a concern in data management, timestamps serve broader purposes in process mining beyond just security verification.
