Alright_meow,
I am experiencing the same problem you had:
"In my system i have 3 PXI chassis that each are controlled by a PXIe-8880. Each PXI chassis has a PXI-6683H card. I have a Cisco IE 4000 setup as a PTP time source, which it connects all the 6683H cards together. Two of the chassis timestamps sync. One does not."
With my system, two out of three of the cards do not sync. In addition, a reboot of the two incorrect chassis causes them to sync 6 hours behind UTC instead of correctly being 6 hours ahead of UTC for our Mountain time zone. We've also seen goofy reported time stamps of 1903 which is apparently the 6683H's default value.
I am curious if you ever determined the exact cause and, or whether your system has experienced it again.
Thanks so much,
