These machines are so old they don't even have a real time clock, let alone any CMOS RAM on the motherboard. You change the BIOS settings by flipping physical switches, and DOS would prompt you to set the time and date on every boot!
This particular machine does have a clock on a "Tecmar Captain 200044" expansion board - if you have a manual or software for that I'd be very interested. I've found no information about it on the internet (other than people selling them, so it must have been fairly popular at one point).
