Yes, computers that are aboard rovers and landers which are being used for scientific purposes. Nobody needs timekeeping on Mars beside folks at mission centers or enthusiasts - even I don't know how long Perseverance is on Mars in Sols and what's its current Airy Mean Time (I'm aware its there and doing good atm). Now, if we'd be there already for decades or even centuries with permanent settlement then perhaps we'd have some date and time formats that would be similar to what we're having on Earth (or maybe they'd use the exotic decimal time) and I wouldn't be even writing the parent comment in first place.
