Description
wanted behavior is that when cmos battery is disconnected because externally flashing, next boot sets the clock to time of build which is 1969 < 2023 and heads will guide user to set clock once and cmos batter yshould keep clock time drift as minimal.
proper time is needed for displaying propr TOTPM in UTC timezone with really low discrepency (<5 seconds causes issues while master shows TOTP with time at each seconds when booting default boot entry prior of prompting for DUK passphrase)

Research direction
Search the repository for CONFIG_USE_PC_CMOS_ALTCENTURY and inspect how it is defined across board configurations. Confirm the setting is absent where external flashing disconnects the CMOS battery, then verify that the next boot initializes the clock to the build time and preserves accurate time for UTC TOTP display.
