And the missions that actually reached Mars chose clocks based on  
Solar time.

Physicists speculate about the laws of physics.  Why not authors?  The  
point being that a typical Asimov story was representative of the  
"Campbellian" mode of positing some delta universe to our own and  
rigorously deducing logical consequences.  One doesn't speculate about  
technology alone, but rather, its impact on humanity and other  
intelligent species.

Niven's FTL spacecraft make voyages to neutron stars and the center of  
our Galaxy.  But it is the effect of these voyages on Beowulf Shaeffer  
that makes the story.  That is, the stories of even the nerdiest  
practitioners of this nerdiest profession still hinge on characters  
and the theatricality of their experience.  Not much has changed since  
the original Beowulf, other than the media used to tell the stories.
