My kernel has local changes...

Apparently UEFI sets a clock value which predates the timestamp
in the root superblock by 47 days.

Since there is no clock, UEFI seems to take the time from it's
build time:

% date -d '10/19/2021 + 47 days'
Sat Dec  4 23:00:00 CET 2021

Without UEFI you start at 0 and get a 'no TOD clock present' message
instead. For a real fix you need a real-time clock plus driver, there
are I2C clock chips that should work.
