clock not set on boot

Ever since updating to 6.8, I've had trouble with the system clock not getting set on boot.

I know the easy answer is to script a call to rdate, but that feels like a bandaid solution.

I'm running from an EdgeRouter Lite (octeon) that afaik does not have a persistent clock. Before 6.8, I always saw boot messages about how the kernel was going to set the clock based on the filesystem. I don't see those messages anymore, and instead see an ominous "WARNING: CHECK AND RESET THE DATE!"

I assume there's been some changes into how dates and time are handled, but I haven't seen anything in the release notes.

Can anyone point me in the right direction, or have a better bandaid idea than calling rdate?
