The document tell is how to get the offset by r36 release.

How to get the clock source offset_ns on Jetpack 6

The offset_ns can be calculated with below API for rel36 ， please try it: uint64_t readOffsetNs() { unsigned long raw_nsec, tsc_ns; unsigned long cycles, frq; struct timespec tp; asm volatile("mrs %0, cntfrq_el0" : "=r"(frq)); asm volatile("mrs %0, cntvct_el0" : "=r"(cycles)); clock_gettime(CLOCK_MONOTONIC_RAW, &tp); tsc_ns = (cycles / frq) * 1000000000; raw_nsec = tp.tv_sec * 1000000000 + tp.tv_nsec; uint64_t offse…
