I applied the lttng patch to the driver domain kernel and instrumented the driver domain. I have a question about the timestamp in the textDump output. From my understanding, the timestamp is in sec.nanosec format, so the difference between two entries is also in sec.nanosec format. However, if I take the earlies and latest timestamp within a trace as the duration (hundreds of thousands second), it is much longer than the actual time I enable the tracing on (at most a minute). Am I interpreting the timestamp wrong? Any input is appreciated and thanks in advance. Thanks, Ya-Yunn
