In the development of an incident timeline, a time based on calculations that may or may not be relative to other incident events is referred to as "absolute time." This concept relies on specific timestamps that are derived from data or measurements, rather than being contextualized by the sequence of other events. Absolute time can provide a precise reference point, but it may lack the relational context that helps to understand the overall progression of the incident.
