I built a TrueNAS Scale 22.02.4 machine recently. It uses the AS Rock EPC621D8A with 64 Gigs of ECC, 10 - SeaGate Exos 6Tb drives, 4 - MVME drives for boot and log pools.
I have tried several fixes for setting the time correctly. I initially set the motherboard (MB) and software time to the local setting. After searching for a fix, I set the MB time to GMT / UTC to 0 and the TrueNAS time to local. I also tried reversing this. Then I tried the same things with a restart.
