Abstract
Time correction records are created for correcting timestamps of network logs to identify timing of network events in a predetermined time reference frame, the network logs being created by logging devices generating the timestamps in device time reference frames. For each logging device, one or more network events are generated or identified at respective event times in the predetermined time reference frame, each network event having a corresponding event-related network log from the logging device and a respective timestamp in a device time reference frame. For each network event, a respective difference value is calculated as a difference between the event time and a respective timestamp from a network log. For each logging device, a selection function is applied to the difference values to calculate a correction value, and the correction value is stored along with an identifier of the logging device in a time correction record.
