What Time Is It?

So there is an easy answer for this on Earth now that us fancy monkeys have figured out that it is efficient to make zones for time. But that system makes basically no sense once we are on the moon, in orbit, on an asteroid, or on Mars. How the ‘f’ do we figure out what time zone Jupiter is in? Well…good news for you…there isn’t any good news…unless we have some sort of human-universal time, we are basically going back to the time when every town set their own clock.
