Ah, ok. I can definitely understand your frustration since exoskeleton and aerodynamic efficiency don't generally mix.

I can't speak for the rovers, but in my experience you start with the UTC time and the convert to a UT1 for space launches. We have to correct for the difference, which is called DUT1: https://en.wikipedia.org/wiki/

It's hard to get a sword into play against massed pikemen. And you want massed pikemen against the heavy cavalry of the period. Also swords expensive compared to spears.

I mean it's a necessity in that you need an elastic supply of labor to respond to the market forces that ostensibly drive a free market economy to meet the needs of its participants.
