Jetson xavier nx and jetson tx2 Clock accuracy

hi,Our team is using the jetson series products to develop accurate and better synchronization systems, but there are always some problems. We suspect that the jetson series products have low clock accuracy. The accuracy we need is 6 hours offset 1ms. (By the way, the maximum accuracy we can accept is an offset of 1ms in 2 hours)

You can use OSC clock having frequency 38.4MHz to synchronize your system with most accuracy.
