Hi, Nvidia I wanted to get the exact time for the image to arrive at the soc, but I found that the timestamp benchmark on RCE is different from Linux, which is a very big challenge for our overall time synchronization, because we rely on Linux to get the trigger camera timestamp, and at the same ti…

The key point is the offset_ns, which is used to calculate the capture timestamp from system time. it’s based-on below formula, clock_gettime(MONOTONIC_RAW) = cycle_ns(TSC) - offset_ns

Can RCE timestamps be synchronized?
