How is the hardware clock connected? It it is something serial it could be an offset by 1 bit.

If it's an x86 laptop, it will be compatible with the MC146818 chip found in the original IBM AT, and return the time in BCD format as yyyy/mm/dd hh/mm/ss.

On modern systems the simulated MC146818 is part of the chipset.
