This is the case across all Blackmagic Design cameras as far as I know, and has been discussed on some previous threads. Unlike other cameras that have an internal battery to maintain clock time, the Blackmagic cameras use a supercapacitor that loses its charge over time. Normally if you use the camera every day it should maintain time, but if you let it go unused for several days or weeks you have to reset the time before you use it again. Often the simplest way to do that is to connect it to a computer using USB, which will reset the date/time automatically and accurately without you having to go into a menu.
I'm using the older BMD cameras (original Pocket and Micro) and the time starts drifting very quickly if you haven't used it for a day or so. I think the newer cameras hold their charge longer.
See for example (this thread is about the BMPCC 4K but applies to the 6K and other cameras as well:
