Re: NetBSD-10.0_BETA: clock: unknown CMOS layout

I would hope that it is the other way around, if >=70, assume 1900, and if < 70, assume 2000 (which is why 22 now will produce 2022). | This heuristic will fail 2030. 2070 would be more likely.But given how very unlikely it is now that anyone is ever going to (legitimately - people doing weird things can deal with the issues) boot a system in the 20th century, ever again, then perhaps we should be altering the heuristic to assume all years are 21st century for now, and then in another 50 years or so, if systems still exist with this issue, and we are still measuring civil time the same way, change the heuristic again so that 22nd century years will work with a similar boundary to what was used for 20th/21st century years, until sometime into the 22nd century, where it can start assuming all boots occur in that period (and so on, for as long as this is needed). kre

The century is then deduced as 1900 if the year number is less than 70 and 2000 otherwise. This heuristic will fail 2030. Then the clock will start with a date 100 years in the past and gets corrected later during the boot process. Ugly, but probably not fatal.

It's a DIAGNOSTIC message, if you run NetBSD-9.x release, the kernel is built without DIAGNOSTIC checks and messages, but NetBSD-10.0-BETA still is.

Windows stopped requiring that level of hardware compatibility some time ago and manufactures (naturally) use the new options. Parts of the "fallout" is hidden by ACPI glue. We are lacking a few drivers in that area, I see the same when booting NetBSD on my wife's notebook. Older NetBSD versions just did not print the message (but the CMOS/clock did not work any better with them). Martin
