Question about raw-data timestamps

[schaeferjakob]

Good day,
I have a question about the timestemps that are output during RF data recording. For example, I get timestemps in the following range: 31148905530 or 159072459760. In seconds, these would be approximately 30 and 160 seconds respectively. To which start time do these refer?

we're timestamping based on the monotonic clock output: https://linux.die.net/man/3/clock_gettime
