This is the arrangement in Kim Stanley Robinson's Mars trilogy.
And the Honor Harrington books, which is where I got it from.

The length of a Martian solar day is currently about 88775.24409 s (per
Wikipedia), yielding an average minute length for a UTC equivalent of
61.6494751 s. On Paleoterra you'll want an average minute length somewhere
between 58.0 s and 59.4 s. So on Mars you'll want about 65% of minutes

would, I imagine, have an impact on timekeeping in this colony.
The magnitude of this difference is in the same ballpark as the present
difference between Terran and Martian days, so exactly the same range

The decimal day is quite practical. It doesn't catch on on Earth, of
course, because of the network effect favouring interoperability with the
existing sexegesimal division. On a new

How would the people on this list who advocate for various treatments of
future timekeeping in our own world deal with that situation?
Fun question. Thanks.
I'd setup two separate timekeeping systems.
For measuring time (and frequency) in scientific experiments, I'd use some
fixed unit and

It depends what project the electrical engineers are working on. Astronomical
