It seems about as silly as Antarctic bases observing daylight saving time. Which several do. The Amundsen-Scott base at the south pole maintains New Zealand civil time, including DST. So its clocks are an hour further ahead in the southern summer, when the sun is continuously above the horizon, than they are in the southern winter, when the sun is continuously below the horizon. In both cases the motivation is to stay synchronised with the other end of supply/command chains. A native Antarctic culture probably wouldn't come up with (or copy) the concept of DST, and a native Martian culture certainly wouldn't track the LOD variations of the neighbouring planet. I think these situations are both silly, and that the predominant local timescale should be responsive to local needs. -zefram
