I think it would be better to have two separate clocks, one tracking solar time with arbitrarily defined beginning, one UTC. Both would rollover after 23:59:59.

It's easier to explain that a second on Mars is longer because it's spinning slower than all the quirks of rollover at an seemingly random value.

The meaning of seasons on Mars would evolve with how we understand the impact of martian weather on daily life. Try to explain winter to someone living all his life on the equator.
