Hi Mark, Confirmed that UEFI firmware v1.19 has a problem with the current snapshot when Device Tree mode is enabled. I switched to UEFI v1.18 and it works. I remember now that this is what Raspberry Pi 3B dmesg has which shows "dsxrtc0 at iic0 addr 0x68". Please see attached dmesg outputs with pre-NTP and post-NTP sync. After synch'ing with NTP, the system clock retains its obtained date and time even when it is shutdown and disconnected from the internet.
Thanks a lot Mark!
