Not really time/date specific.  unit-specific, perhaps:

(format-mixed-radix-number nil (+ (* 360 60 60) 145210.5) '(60 60  
360) '("~,2F''" "~D'" "~D°")) => "400°20'10.50''"
(format-mixed-radix-number nil (+ (* 360 60 60) 145210.5) '(60 60  
360) '("~,2F''" "~D'" "~D°" "~*")) => "40°20'10.50''"

Perhaps.
