Abstract
Sensor device times can vary and may be set significantly wrong. In one embodiment, the present invention can adjust a sensor's time by receiving a raw security event from a sensor device, determining whether a timestamp included in the raw security event is within a timerange around a time known by the agent, determining whether a time offset is in a non-initialized state, and determining whether to adjust the timestamp by applying the time offset to the timestamp, the determination being based on whether the timestamp included in the security event is within the timerange around the time known by the agent and whether the time offset is in a non-initialized state.
