The system BIOS v1.04 or older has a technical limitation to clear the CMOS (NVRAM).

When the procedure of clearing the CMOS is performed, if you do it without disconnecting the AC cord, time

and clock will be reset to 2001-01-01, 00:00. When the CMOS clear process is performed without disconnecting the

AC cord, the Server keeps Date and Time. After that, when you disconnect and re-connect the AC cord, Date and

Time will be reset.
