Because a mean solar clock is automatically a stable subdivision of  
the calendar - stable over long periods of time as well as  
geographically.  Noon on two different days is separated by an  
integral number of days no matter what period of time separates the  
two dates and how the length of day may have varied in the interim.

There is no swizzling needed if civil timekeeping remains tied to the  
Sun.
